• Global glaciers retreated = more fertile land available

• Agriculture invented ~10,000 year ago

  • Farming technologies: ex) iron plow

  • New strains of crops

• Population limiting factor = amount of food being produced

• ~1300 = pullback from the Black Death

  • Modern chemical industry = modern fertilizers

    • More productivity from farmland

Limiting Factors

Climate Niche

The climates in which it is ideal for humans, and many animals, to live is shrinking due to climate change. With that being said some humans do choose to live in extreme conditions due to heritage or work opportunity. Another problem is that we generally like to settle near coastlines which are vulnerable to erosion and rising sea levels.

“Earth has more trees than it did 35 years ago - but there’s a huge catch”
(WEF, Aug 30, 2018)

”The study points out that industrial timber plantations, mature oil palm estates and other specifically planted forests add to global tree cover.”

Food supply

Climate change also affects the amount of land that can sustain agriculture. There are many efforts to prevent desertification, but it is hard to deter severe weather patterns causing damage to crops.

The future may hold more greenhouses for agriculture as it proves resilient against inclement weather and even facilitate growing in arid conditions. Ultimately, this relies upon profit viability and a cost benefit analysis of expensive infrastructure versus traditional agriculture. I believe it will only become more incentivized through innovation in automation, transportation, and more.

100% Renewable Economy Timeline

Economic Efficiency

“Modern Waste is an Economic Strategy“ (Discard Studies 07/09/2014)

“About ninety-seven percent of waste produced in the US today is industrial solid waste (ISW) produced during processes such as mining and mass agriculture. The remaining three percent is what we usually think of when we think of garbage: municipal solid waste.”

Carbon emissions could be considered an economic inefficiency in the sense that it is a negative externality to life on Earth. A fully circular and sustainable economy would prevent many negative externalities such as chemical pollution and habitat destruction.

Fertility Rates

Globally fertility rates have already peaked and many countries are below the replacement rate of 2.1 which means there is continuously less and less young people than old people.

Population Demographics

This is the real problem with declining populations. Pension systems can often rely on the economy that is supported by the taxes of the young working population. For as long as we have known GDP has been steadily growing and this has meant taxes provided a justification for increasing government spending. However, this will not always be the case if population starts declining, although humanoid robotics may change this dilemma. Currently, many governments sit in budget deficits (spending more than they’re making) with immense amounts of debt. This debt must be paid off sometime somehow and it is passing the buck to the next generation. As a techno-optimist I want to believe that innovation in the 21st century will usher in a post scarcity economy, however if this does not happen then future generations are fiscally ruined.

The Overpopulation Myth

The Earth could sustainably support 10x the current global population, given the necessary innovation, investment, and infrastructural change.

Thomas Robert Malthus, an English economist, in 1798 proposed the theory of a “Malthusian trap.”

This “Malthusian trap” predicts that the human population has a hard limit given the available resources on the Earth, and modern pundits may tell you that our current global population has reached near that limit. Well here on this blog I argue that this is simply not true.

The Labor Market

A large part of modern discussions about the labor market and economic systems is based off of things like Keynesian or Marxian economics. However, these theories were only invented less than 200 years ago. Sometimes I wonder about the preoccupation of these structures when economics is most definitely a soft science, meaning that we have no empirical basis to make judgements or conclusions. With this being said let’s discuss some of the common tropes of “economic problems” caused by “overpopulation”.

Lump of Labor Fallacy

“Countering the “Lump of Labor” Fallacy: Two Lessons” (Jan 6, 2021)

“The “lump of labor” fallacy is the assumption that there is a fixed amount of work.

It's a tempting idea to some because it seems to be true. For example, jobs can be lost to automation and immigration,” Wolla wrote. “However, that is not the full story.”

If the fallacy were true, jobs could not be created, just redistributed, he wrote. The essay outlined two “lessons” that run counter to the fallacy:

1. Job losses in one industry can support growth in other industries.

2. The economic “pie” is not a fixed size.”

Structural Unemployment

The answer to structural unemployment is simply education. Obviously this costs money, but I think cultivating a culture of continuous learning, especially in an age of such abundant information, would be just as impactful.

‘Cities of the Future’

In order to house such immense populations we must rethink how we build cities. Nowadays, there are many who claim to be building cities of the future, but quite unsurprisingly these projects turn out to be burning money pits that are eventually abandoned.

I will discuss more about urban planning & organic growth of cities in other posts, but for now let’s theorize how to sustainably house billions upon billions of people without sacrificing quality of life.

AI, or artificial intelligence, has been a hot topic as of late. However, some might not understand what ‘AI’ really means.

Google mentioning AI about 25 times throughout their latest keynote

When Big Tech companies refer to AI they are most commonly referring to deep learning applications: deep learning is a specialized form of machine learning, but what is machine learning?

Machine learning is often characterized as a manifestation of statistics and this technology is nothing new.

The term AI can encompass many forms of mathematics such as knowledge graphs or logic engines, but these are not classified as machine learning. The key difference between AI and machine learning is that an ML system is able to learn from new data.

So if deep learning is what people are actually excited about, what is that exactly?

Deep learning relies upon an intersection of AI and data science, leveraging deeply layered neural networks to learn hierarchical representations from big datasets, which enables predictive analytics, classification, regression, generation, and more!

Neural Nets

Latent Diffusion

AI Ethics

Many are ringing the alarms concerning the ethics of deep learning models and the dangers of super-intelligence. However, to have any ability to consider this in any practical sense we must focus on model interpretability to truly understand what is going on behind the scenes.

HellaSwag: Can a Machine Really Finish Your Sentence? (May 19, 2019)

“In this paper, we show that commonsense inference still proves difficult for even state-of-the-art models, by presenting HellaSwag, a new challenge dataset. Though its questions are trivial for humans (>95% accuracy), state-of-the-art models struggle (<48%). We achieve this via Adversarial Filtering (AF), a data collection paradigm wherein a series of discriminators iteratively select an adversarial set of machine-generated wrong answers.”

Semi-annual update of the top 500 ranking supercomputers in the world (top500.org)

The current approach to improving model performance seems to be exponentially increasing parameter sizes. The reality is that we must make models more efficient to run on less powerful devices like phones and be more energy efficient. It is a matter of working smart versus working hard.

Most deep learning models run off of powerful GPUs, typically Nvidia due to CUDA core compatibility with mainstream software, and this is either done by cloud with AWS/Azure servers or an expensive computer. Apple Silicon recently started a huge trend where manufacturers are prioritizing ARM chips due to their affinity for machine learning calculations and power efficiency. Now, Intel, AMD, and other chip manufacturers have also begun to release products in this regard.

One huge problem we will encounter is the exponentially increasing difficulty of fitting more transistors into the same space. The physical size of each transistor has become so small that quantum effects are starting to interfere with the electronics. As we gradually approach the limit of the current transistor paradigm we must consider where to go next.

A few prospects are emerging which could push us to a new era of computing including quantum computing and superconductors, but ultimately the effects of quantum tunneling when dealing with < 5 nanometers means that chips will just have to grow in size for compute hungry tasks.

Physical AI

Bio-Computing

It is hard to determine when a computer will obtain consciousness or surpass the computing power of a human brain. The question itself is hard to determine: Can binary programming mimic natural neurons? What is the theoretical computing power of a human brain? Are our neuron interactions quantum based? (Our noses are) How do we define what is consciousness?

Ultimately, biological systems may be more robust. There is so much more to learn from the mechanisms of nature. Life is truly the ultimate technology. You may be shocked to discover that the intelligence of individual cells is underestimated. I will be covering more about Michael Levin’s research in another post!

Moreover, there is so much more about neuroscience that we have barely discovered.

The most advanced computers may eventually be biological computers with engineered neurons.

The ML Papers That Rocked Our World (2020-2023)

Many scientists theorize that anthropogenic change is creating the conditions for a 6th mass extinction event. The background extinction rate gives a constant to compare against and it is clear that the extinction rate is accelerating.

As you can see above, the rapidly changing conditions of the Anthropocene is affecting animal groups differently.

Invertebrates are even seeing a surge in population.

During periods of rapid change several characteristics may contribute to the resilience of a species: behavioral variability, high reproductive rates, broad geographic ranges, flexible diet, and adaptability to various habitats. This is the way of nature and how mammals came to dominate the Earth after the Cretaceous-Paleogene mass extinction event; when the dinosaurs died off from a major asteroid impact.

The extent of climate change will depend on the collective actions of our global civilization, but rest assured life will likely never go extinct. However, it is important to understand that humans thrive off complex ecosystems supported by rich biodiversity.

IPCC 2022 Report

The IPCC Report “assesses the impacts of climate change, looking at ecosystems, biodiversity, and human communities at global and regional levels. It also reviews vulnerabilities and the capacities and limits of the natural world and human societies to adapt to climate change.”

https://www.ipcc.ch/report/ar6/wg2/

Atmospheric Physics

One thing that the report emphasizes is the role of atmospheric physics in climate change. Many of the phenomena are still unable to understood due to their complexity, but we do understand that as greenhouse emissions increase there is a domino effect of warming, especially at the poles.

Moreover, these changes can disrupt global wind patterns causing severe weather patterns and drastic changes in climate across large regions.

We must not underestimate the destructive capabilities of mother nature. As the climate warms there will be more ocean water, and this could lead to unforeseen disasters apart from rising sea levels. Large volumes of water are a terrifying force under inclement conditions.

Climate Alarmism

The ultimate realization we must make is that our current civilization is extremely dependent on the infrastructure we have built over the 20th century. This infrastructure was built with primarily fossil fuels in mind and it will take time for nations to transition, let alone afford, renewable and circular energy infrastructure. On the topic of affording infrastructure investments, oil is the basis of the world economy and essential for financial growth.

Our Industrialized World

“Why Demand Destruction Is More Worrying Than A Supply Crunch In Oil Markets”

Developing Countries

The problem with net zero climate programs is that poorer countries are disproportionately affected. Rich countries are already industrialized and burned a lot of fossil fuels to get there. Also, geographic disparities can put many nations at an inherent disadvantage for building a sustainable economy. Geographic determinism is a huge part of the history and future of nations.

“Biden’s green energy law is turning out to be huge” - Aug 7, 2023

“US green energy law is turning out to be huge. The Inflation Reduction Act tax incentives are way more popular than expected. Nations in Europe and elsewhere are rattled by the possibility that the United States might now capture an outsized portion of the global green energy economy.”

“One year after passage of the Inflation Reduction Act estimates have already tripled from original CBO projections. It has created a flurry of investments in new factories and clean energy projects. Some economists are crediting it with a new US manufacturing renaissance. The tax incentives are in place for ten years and have no cap or upper limit.”

Damage Control

Fortunately we are growing more environmentally conscious and developing ways to reduce our impact on Earth without human sacrifice. We are able to engineer our way out of this, but it will not happen overnight.

Career Specialization

The biggest question I have faced during my early 20s has been which area to start specializing in for my career path. I’ve always wanted a skill set that is flexible and could adapt to unexpected changes in the 21st century.

I feel very blessed to have landed an opportunity to intern at an automation engineering company next summer. In short, they are an advanced mechatronics provider where I will gain industry experience with computer vision, data engineering, components manufacturing, and more!

My ultimate goal is to move to the US and pursue opportunities at deep/hard tech companies. Here are a few exciting companies of the 100s that are popping up nowadays.

What to Expect

I won’t be sticking to any particular structure like last year, but I will be releasing a few delayed posts from last year including:

1. The Anthropocene Extinction Event

2. Neural Nets & Biocomputing

3. Homo Techno #7-9

This year I will be posting a lot more topics involving data science as I focus on my career development, however I will sprinkle in some subjects of personal curiosity similar to the regular posts you have been seeing. Thank you again for being a subscriber and I encourage you to share my blog :)

Also, if you found/find a certain topic interesting feel free to reach out by replying to any of my emails. My free blog posts only cover the surface level of complex ideas and there is always more to discuss; I am always open to guest authors!

Water is something so essential to life, but yet another thing we have commoditized. The topic of water is growing to become important in geopolitical and existential conversations.

Freshwater Access

There is no shortage of water itself on planet Earth, however freshwater is what is useful to human beings. Therefore, we rely on rivers and lakes for all the water we use. The problem nowadays is that dry places are getting drier, all the while we are using more water; this is leading to an inevitable decline in water supplies.

Water Diversion

Desalination

The salty water in the ocean must be desalinated to become anything useful and this process is very energy intensive. Unfortunately we do not yet have fusion reactors so energy tends to cost a lot! Good news is that we are developing cheaper better ways to desalinate water, but we will have to see whether these technologies can scale.

Freshwater Eutrophication

Water Pollution

Micro-Geoengineering

Practice for terraforming.

Tangent: Sulfur Emissions

Turns out we have been doing geoengineering for awhile now. Cargo tankers used to emit a lot of sulfur emissions because of the particular fuel they used. Recently we have started to phase out these fuels for sulfur free alternatives and as a result we have discovered these sulfur emissions have been deflecting some solar radiation. This switch to cleaner tanker fuel has inadvertently warmed the planet more and left us the important takeaway that geoengineering is already happening. Many have argued that geoengineering is too dangerous or unethical, but this perspective can now be approached with some skepticism.

Land Reclamation

Shoreline Protection

Holistic Land Management

We are seeing a growing movement of holistic land management technique such as permaculture where we utilize nature to enhance our environments. Water can be retained in the landscape through trees/vegetation and reservoirs (lakes, ponds, swamps, flooded forests, aquifers). This results in a decrease in ambient temperature, resistance to wildfires, increased biodiversity, and more! There are so many things we can learn from the wonders of our natural world.

Stormwater & Grey Water Management

Many cities have antiquated infrastructures that manage stormwater and waste water in unproductive ways: such as mixing them together and pumping it all to a treatment facility that has a limited capacity. We have now learned to design our cities better, but it takes a lot of time and money to update infrastructure. Hopefully we can be more proactive about the ways we design our cities including their relationship with water/nature.

Hydrothermal Carbonization

Turning waste into useful resources.

Since the dawn of complex civilization, enabled by agricultural technology, we have relied heavily on soil fertility. Plants require a variety of macro and micro nutrients.

For this reason we initially settled areas rich with river sedimentation. This sedimentation is exactly what creates fertile soil, however there are a few other contributors to soil fertility.

The Mesoamericans utilized floating garden pads in lakes and symbiotic relationships akin to permaculture principles to create fertile growing conditions.

Another case would be volcanic soils which are extremely fertile. Which is exactly why Java has an incredibly high population density.

Artificial Fertilizer

One of the most important factors in the relatively recent global population boom was the widespread use of artificial fertilizer. This enabled far more crops to be grown than before. However, we now live in a world where we have fertilizer suppliers and dependent countries.

Every year the global demand for fertilizer grows and I am sure this will become a growing geopolitical issue.

Soil Dysbiosis

Fertilizer demand is also growing because of poor agricultural practices leaching nutrients out of fertile regions. Modern agriculture relies on monocropping, pesticides, herbicides, and other modern industrial practices.

Fortunately there are techniques to combat this and preserve, or even restore, soil fertility naturally. You may have heard how earthworms are good at eating and further decomposing organic matter in soil, thereby increasing soil fertility!

The Climate Crisis = The Food Crisis

The industrial food complex that supports modern populations is based off the climate we were used to in the 20th century and before. As the climate crisis starts to change weather patterns, many regions of the world will experience drastic changes. This may affect some less than others, but overall the instability of weather will increase.

While increasing severe weather patterns may be escapable to some extent, the resulting damage to agricultural industries will not be escapable. Food will become increasingly scarce and prices will soar.

New Age Agriculture

This is where a technological solution may come in. Food security is a big concern as it is a basic human need. Fortunately we are starting to see the rise in use of aquaculture, vertical farming & other advanced agricultural techniques. This new age farming contains a variety of benefits including no pesticides/herbicides, increased nutrient density, and resistance to drastic weather patterns since a lot of these operations are indoors!

Vertical Farming

Now the 2 major challenges with a lot of these techniques is power consumption and initial material cost. However, in the long run it may become far cheaper than traditional agriculture through a variety of means: becoming cheaper through economies of scale, cost per use declining after initial investment, and increasing yields through iterative system design.

Soilless Growing

An interesting thing with vertical farming is that it usually utilizes soilless growing techniques. Below you can see 3 different methods: aeroponics mists the plant roots, deep water culture keeps the roots submerged, nutrient film technique where a thin layer of liquid is maintained below the roots. Each method has its benefits and drawbacks such as water usage, system complexity, and resistance to disease. The drip system is also mentioned which uses soil, but has constant micro-irrigation saving water and efficiently delivering nutrients.

All of these systems utilize nutrient solutions to feed the plants in contrast to natural soil fertility. From what I’ve seen in the cannabis industry, plants grown using soilless methods achieve higher yields and quality of crop. Of course this relies on the care and attention of the growers, but generally it is superior.

“Study finds high blood and urinary metal levels among exclusive marijuana users” (Ground News)

A new study conducted at Columbia University Mailman School of Public Health suggests that marijuana users may have high levels of toxic metals, including lead and cadmium, in their blood. The study found that the cannabis plant absorbs these metals from the soil and deposits them in the leaves and buds, which can then be inhaled by users.

Soilless growing also circumvents this problem of heavy metal accumulation in some plants.

Smart (AI) Management

Instead of using herbicides and pesticides, many agricultural companies are turning to technology. AI powered technologies can keep track of and maintain crops preventing the use of nasty industrial chemicals to keep pests and weeds away.

Genetically Engineered Plants

Contrary to popular opinion, GMOs are not all evil and bad. This perception comes from the way big agriculture companies have prioritized profits over equitable food production: seed privatization, planned obsolescence, and decreasing nutrient density. In the wrong hands any technology becomes terrible, but it is all about the method of application. Genetic modification of plants has actually existed for quite awhile under conventional breeding or hybridization: increase crop yield, hardiness, and new attributes like color, flavor, or other appearance.

Livestock

Now livestock is an industry that will likely not change drastically, however as these new age farming techniques grow in popularity the amount of land used for agricultural practice will decline due to increased efficiency. Therefore, we will have a lot of free land for pastures.

I think that there is a sustainable way to raise cattle, however it does not involve industrial practices like grain feeding or cramped barns. As you can see in the diagram above, nature made cattle to be incredibly efficient in the biological circular economy. 14.5% is a significant portion of the global emissions, but I think the importance of animal protein cannot be ignored.

Synergistic techniques like solar grazing where livestock is used to clear the plant overgrowth in solar farming fields may be able to help, and a fully sustainable grid could feasibly sustain carbon capture.

Some theorize that we will create meat cell tanks instead of raising cattle because it is more resource efficient, but some others argue that this is not an actually feasible idea as it will take a significant amount of time before it is even cost competitive with real beef. One could also potentially argue that the micro-nutrient diversity and density that comes from a pastured cow cannot be paralleled by industrial alternatives.

Dairy on the other hand is simpler to synthetically produce using biomanufacturing!

Aquaponics

Why is this important to you? Plastics are a common example of a synthetic polymer and they are used in every aspect of daily life from food containers to home sealants. In fact, plastics are so important that we are essentially dependent on them.

The problem is that plastics are made from fossil fuels [hydrocarbons].

We are only recently learning the problems that come with plastics such as microplastics and endocrine disruption. Plastics’ slow degradation also poses an issue of environmental persistence as it takes UV (sunlight) & a long time to break down. Recycling tends to use more energy than generating new plastic and it is not a long term solution.

A good question to ask is, what if the plastics were biodegradable in the first place? This is why some are discussing the idea of biopolymers replacing this aspect of the economy. Cellulose is the most abundant macromolecule on Earth. We can take advantage of this fact along with other biological tools to transform the infrastructure of the global economy.

Biomanufacturing

Biomanufacturing is set to become an accelerating industry as a growing body of research utilizes enzymes and bacteria in novel manufacturing methods.

Precision fermentation is already disrupting several traditional industries. Engineered yeast are bred in large tanks to produce an array of end products. This can range from pharmaceuticals to skincare & food ingredients to even textiles.

So in this future biotech world we would only need to use agricultural inputs of basically any organic matter (cellulose), and we could produce vast amounts of varied products including bioplastics, medicines, and industrial chemicals. There may be additional benefits like reduced energy consumption, reduced emissions, and increased yield per cost.

Once we convert to a fully electric transportation & sustainable grid economy the demand for gasoline, LNG, and diesel would drop significantly. Similarly, biomanufacturing would work to diminish the demand for hydrocarbons in plastics and even industrial chemicals. This would effectively destroy demand for crude oil and would work to significantly reduce emissions. There are so many other health, environmental, and economic benefits we would reap from this future ideal economy!

The Polymerist is another Substack blog that I stumbled upon recently that discusses this in depth. The author is a PhD in polymer science and definitely knows whats he’s talking about.

Tangent: Engineered Bamboo

When plants grow they use CO2 to construct their cellulose walls. The fastest growing plants on Earth are the bamboo family. Their species are diverse and can range from cold hardy varieties to tall tropical giants.

There are 2 main types of bamboo: the clumping kind, and the running kind. The running kind is known for being extremely invasive because it will grow its roots deep underground and keep shooting up new stems far away. Bamboo is known for its excellent carbon sequestration abilities and that makes me wonder why we don’t grow more of it.

There is an interesting story of how Norman Borlaug utilized GMOs to increase the hardiness and yield of plants. The amount of lives he has saved from famine are innumerable. We could achieve a similar effect with GMO bamboo and reforest vast areas of unproductive land. This would soak a large amount of carbon and generate harvestable forests for cellulose.

Aside from being a cellulose source, bamboo is a great wood to use for a variety of applications: construction, furniture, flooring, kitchenware, charcoal, and even fabric (Tencel).

Modern Biotech

The term biotech covers a wide range of technologies, but generally it is comprised of an integration of the natural sciences and engineering to create new solutions.

Here I will be covering medical biotech, but I will expand upon industrial, agricultural, and marine biotech in the next few posts.

Molecular Diagnostics

Definition: sometimes called molecular pathology, it involves taking DNA or RNA and analyzing the sequences for red flags that can pinpoint the potential emergence of a specific disease.

Gene Sequencing

The field of molecular diagnostics has expanded rapidly in recent years, in part, due to the swift decline in cost for gene sequencing technologies.

CRISPR/Cas9

We used to think that gene editing had to occur at conception, so only for newly developing fetuses. However, CRISPR technology has enabled gene editing in vivo, meaning it is possible to genetically engineer fully matured human beings.

The Next Pandemic

Emerging Pathogens

“Zoonotic Mutation of Highly Pathogenic Avian Influenza H5N1 Virus Identified in the Brain of Multiple Wild Carnivore Species” (Jan 20, 2023)

Fungal Infections

Currently, we have no way to cure fungal infections. Anti-fungals do exist, but they are developing drug resistance much like bacteria. Fungi also share similar biochemistry to our bodies so it is trickier to combat with contemporary medicine. This is a problem we have not encountered on a larger scale, but hopefully research into combating these infections will grow as the years progress. The world of fungi is incredibly fascinating, and an area of science we do not know much about yet.

“Truth is stranger than fiction, but it is because fiction is obliged to stick to possibilities; Truth isn't.” - Mark Twain

“Brave New World” published in 1932, by Aldous Huxley, is a dystopian novel that depicts a world where a global state brings peace and stability through unorthodox social values and authoritative use of technology. Many would argue there are some stark similarities between this story and modern society. Thankfully we do not have a centralized global government, but we are beginning to see the abuse of technology to surveil the masses.

“NSO Group’s Pegasus Spyware Returns in 2022 with a Trio of iOS 15 and iOS 16 Zero-Click Exploit Chains“ (April 18, 2023)

“NSO Group” (Israeli cyber-intelligence firm, produces government level spyware)

Great lengths are taken to keep a close eye on citizens. “Nineteen Eighty-Four” warns that this absolute grip over society to preserve order eventually results in a loss of humanity: dignity, morals, values, emotions.

This is just one of the parallels we can draw from science fiction stories. There is a plethora of authors that delve into the chaos that technology can release on the world. However, this does not necessarily mean that technology is bad, it is not as simple as that. It just means that the world will change faster than ever, this may present opportunities for bad actors/states to take advantage (dark tetrad/psychopathic personality types, will cover this in the future).

“Chaos is a ladder” - Littlefinger, Game of Thrones (Machiavellian character)

Technological Singularity

Sometimes referred to as “The Singularity,” there is an idea that we are approaching a point where technological growth becomes uncontrollable and irreversible.

“Superintelligence” postulates an AI that can surpass human intelligence. ‘Experts’ predict that this will be possible anywhere from 2028 to 2045, but as always such specific prognistications are usually inaccurate.

What is clear is that it is coming within the earlier half of this century based on the current rate of progress.

Some may even argue that our technology is a natural extension of our evolutionary process. We are starting to see the enmeshment between biology and computer science: brain-computer interfaces, digital neural nets, quantum computing (nature utilizes quantum phenomena!).

British entrepreneur Mustafa Suleyman, and writer Michael Bhaskar, recently released this book above covering 3 industries that are rapidly developing, and will converge to create the biggest revolution in human history: AI, quantum computing, and synthetic biology. I briefly talked about this impending synergistic wave in my previous post.

I will cover the specific industries, and examples of convergence, in more depth with upcoming posts!

Takeoffs

“Distinguishing definitions of takeoff“ (Alignment Forum, Feb 13, 2020)

• Foom/Hard Takeoff

• Hansonian “Slow” Takeoff

• Bostromian Takeoffs

  • Slow

  • Fast

  • Moderate

• Continuous Takeoff

• Gradual Takeoff?

• Paul Slow Takeoff

• No Takeoff

• Drexler’s Takeoff

• Bauman’s Takeoff

As you can see there are numerous depictions of how The Singularity may occur. The manner and point in time at which this may occur depends on endless factors with no real empirical basis. A few concepts we can summate are…

• Inflection points: breakthroughs that accelerate progress

• Hypertechnocapitalism: increasing capitalism, concentration of wealth, through large technology companies swallowing every industry

• Disruptive innovation & legacy industries: old monopolized industries/companies will fight to retain their control against new & rising contenders. For example, Tesla vs legacy auto companies.

I think that this topic is extremely nuanced because of the secondary, or even tertiary, effects that AI could have on society, as well as differences between the micro/macro perspectives of impact. The posts below provided me with some interesting near and mid future outlooks.

A Path to Rationality

One of the key themes in “Brave New World” is that future society starts to accept willful self-delusion. We see this in the “soma” that they consume which sedates them with happy hallucinations, and the world state seeks to prioritize happiness over the truth.

“The Demon-Haunted World: Science as a Candle in the Dark” published in 1995, by Carl Sagan and Ann Druyan, seeks to explain the scientific method to the laypeople and encourage critical/skeptical thinking. The objective of the message is to prevent the rise of pseudoscience, ignorance, and general irrationality.

We must rely on empiricism, statistics alone do not tell us an accurate picture: epidemology studies are often correlatory not causal (meaning they show a relationship with no real evidence of one causing the other). We must observe all information with doubt. Things like peer review, repeatibility of results, and proper causal inference must affirm our conclusions.

Nowadays, sensationalism and politics seems to be the priority of mainstream conversation. This is likely the case out of pure greed for more traffic/profits, and could even extend to societal control/power. There are instinctual psychological phenomena that lead the general population to be more perceptive to negative information. This was an evolved trait meant to keep us alive from dangers like predatory animals.

A Bright Future

I know this post might incite some deep fears about the future, however please do not think that the worst outcomes are inevitable. I believe we can seek to create the best possible future for ourselves, but this comes with hard work. We must be informed, we must take action, we must perservere to create a better future for the destiny of humankind.

“It’s Time to Build“ (Marc Andreessen - A16Z venture capital firm)

As we enter the 21st century we are seeing a significant body of quantum mechanics, chemistry, biology, and interdisciplinary research having wide impacts on society.

In my Homo Techno #6 post I talked about how the 4th/5th industrial revolutions are currently taking effect. The characteristic that sets apart these industrial revolutions is the significant increase in communication, accessibility, and collaboration through digital tools.

This productivity boost benefits all areas of research & development. Nowadays, new discoveries/technologies seem to appear every week! A lot of these technologies are also highly synergistic.

Deep Tech (or Hard Tech)

Definition: a classification of organization, or more typically a startup company, with the expressed objective of providing technological solutions based on substantial scientific or engineering challenges.

Key Characteristics

• Requiring lengthy R&D & large capital investment prior to commercialization.

• Technical risk, while market risk is significantly lower due to clear potential value of solution to society.

• Underlying problem being solved generate valuable IP.

Origins & History

• The term has already been used for decades by major defense & telecommunications R&D divisions: Raytheon, Lockheed Martin, Bell Labs.

• Increasingly used by companies in the venture capital ecosystem.

• Investment activities are concentrated in the United States and China that totaled for about 81% of global private investments in deep tech from 2015 through 2018 with approximately $32.8 billion and $14.6 billion invested in each country, respectively.

• European countries are also active in deep tech investing. According to the Financial Times, in 2017 the total funding towards deep tech companies reached around €3 billion across 600 deals.

Common Fields of Application

• Agriculture

• Life sciences

• Chemistry

• Aerospace

• Sustainable energy

• Computing & cloud infrastructure

“The rapid hard-tech emergence” (June 12, 2021)

“Affordable robotics, AI-driven sensor fusion, uninterrupted connectivity and supermaterials are merging into the technology stack to unlock massive new tranches of value for customers.“

“The last three decades have been defined by “software eating the world,” and it’s been feasting on the lowest hanging fruit. But our screen-based, server-based digital world is increasingly limited to marginal gains in niche markets. As our friends at Ubiquity Ventures say, it’s time for “software beyond the screen.”

Technological Convergence

There are countless more examples of technological convergence. Frankly it is impossible to keep up with all the newest developments!

You could think of each individual technology as a node and the connections between them to be convergent technologies. As the quantity of technologies increases the connections increase exponentially, meaning that mathematically the rate of innovation will accelerate in a feedback loop.

The modalities of regenerative medicine take inspiration from endogenous compounds (chemicals originating within the body). The human body has a natural ability to heal itself in numerous ways.

“Nature is always more subtle, more intricate, more elegant than what we are able to imagine.” - Carl Sagan

“Antiaging protein is the real deal, Harvard team claims” (Science.org)

“Lifelong exercise, but not short-term high-intensity interval training, increases GDF11, a marker of successful aging: a preliminary investigation

^ an active lifestyle literally makes you younger

IGF-1

There are conflicting studies about IGF-1: on one hand it has anti-aging and performance boosting effects, while high blood levels have been linked to cancer development and shorter lifespans. However, exercise has been shown to promote local IGF-1 expression but not systematic IGF-1, and lower intensity aerobic exercise is shown to down-regulate IGF-1 and up-regulate IGFBP-1.

“Effect of Low-Intensity Aerobic Exercise on Insulin-Like Growth Factor-I and Insulin-Like Growth Factor-Binding Proteins in Healthy Men” (International Journal of Endocrinology)

“IGFBP-1 plays an important and potentially beneficial role in regulating metabolic and vascular homeostasis.” (NIH)

“Low circulating levels of insulin-like growth factor binding protein-1 (IGFBP-1) are closely associated with the presence of macrovascular disease and hypertension in type 2 diabetes” (NIH)

Telomeres

Telomeres (the end caps of our genes) also suffer from accumulated damage due to replication: they gradually get shorter due to imperfect cell division.

Currently there is work to research therapies for telomere lengthening. This would help prevent faulty replication as we age (cancer).

There are definitely numerous more pathways we have yet to discover and it seems the pace of research is accelerating! Evidence shows that longevity lifestyles happen to activate a lot of these pathways as well.

Inflammation

The role of inflammation is an overarching theme among emerging medical research that is attributed to all-cause mortality and quality of life. Both acute and chronic systematic inflammation can accelerate the degradation of our bodies. I am excited to expand upon this growing body of research in my inflammation series! Here’s some breadcrumbs.

Longevity Supplementation

Here’s how I would rank the best longevity supplements based on current evidence of benefits & safety. However, addressing any nutritional deficiencies will be far more substantial in benefit! Vitamin D3/K2/B complex are often deficient. Get your blood-work done to know for certain.

1. Creatine (ATP-creatine phosphate system / alactic system)

   1. Saturation levels required = 5g everyday

   2. Improves body composition, anaerobic performance, recovery?

   3. Potential cognitive benefits, studies still coming

   4. Safety proven beyond doubt

   

2. Beta-Alanine (glycolysis system / lactic acid system)

   1. Saturation levels required = 5g everyday

   2. “Beta-Alanine Supplementation Improved 10-km Running Time Trial in Physically Active Adults” (Frontiersin.org)

   3. Possible induced taurine deficiency

   “Taurine deficiency is probably not a practical concern with conservative beta-alanine supplementation (with breaks, to let cells accumulate taurine). Excessive usage of beta-alanine over a long period of time has not been studied in humans, however, so the possibility that it could lead to taurine deficiency cannot be ruled out. Severe muscle cramps can be a symptom of taurine deficiency and could serve as an indicator.” (Examine.com)

   1. Good safety profile so far, needs long term studies

   2. Combination with creatine appears to have even better results than either alone: increased muscle tone/performance

      “Effect of creatine and beta-alanine supplementation on performance and endocrine responses in strength/power athletes” (NIH)

3. [NMN] Nicotinamide Mononucleotide (aerobic system)

   1. Disclaimer: This is an emerging supplement, keep up to date on studies!

   2. Increases health-span significantly, increase lifespan slightly (in rats)

   3. Other metabolic health benefits: insulin sensitivity, mitochondrial function, anti-inflammatory, improved neuronal function, and more!

   4. NMN appears to boost endurance in amateur runners, study finds

   5. Studies are showing good safety profile in early human trials

4. Hydrolyzed Collagen

   1. Supports skin, joint, hair, nail growth

   2. Improves exercise recovery

   3. Better absorption / function with vitamin C / hylauronic acid

5. Magnesium Bisglycinate / Threonate (brain health, relaxation)
   Magnesium Citrate (muscle recovery, relaxation)

   1. Well tolerated (no stomach irritation) bio-available forms

   2. Supports muscle recovery, brain health, and more

6. GlyNAC (amino acid antioxidant) [Highly recommended for ages over 40]

   1. Glycine + NAC (N-acetyl cysteine)

   2. Reverses aging hallmarks

   3. Promotes healthy aging in various ways

   4. Polyphenols are similar

      1. I’m young so I just drink Japanese green tea/matcha

NAD+

• Related to vitamin B complex (multiple vital body functions)

• Significant role in mitochondria function therefore energy production

• Low levels lead to fatigue, neurodegenerative disease, and poor mental health

• Supplementation can help multiple sclerosis

• NAD+ precursors = NMN, Niacin (Vitamin B3), Niacinamide

“The Role of NAD+ and How Increasing NAD+ Benefits Your Brain“ (June 17, 2023)

NMN

Glutathione

• Antioxidant effects

  • Pterostilbene might be better (found in blueberries, almonds)

Longevity Lifestyle

^ A fun thought experiment

Avoiding Premature Death

The 4 horsemen (major killer diseases) are:

1. Cardiovascular disease

2. Cancer

3. Neurodegenerative disease

4. Type 2 diabetes

In my recent healthcare post I covered how these diseases are clearly preventable. They have the commonality of metabolic dysfunction and what follows in this post is a comprehensive lifestyle to combat this. The benefits you could reap extend beyond preventing these diseases and will lead to better brain health, immunity, and more!

Exercise

I covered some exercise related concepts and training methods in the post below. Here I will further elaborate on the physiological mechanisms which extend our healthspans.

Re-Iterating the Importance of Muscle Mass

“Association of frailty and pre-frailty with increased risk of mortality among older Canadians” (Statistics Canada)

I think that this association with frailty and increased risk of mortality could extend even to younger populations. Emerging evidence suggests that muscles play a vital role in numerous aspects of our health including immunity, inflammation, and organ health.

“Muscle is the organ of longevity.“ - Dr. Adeel Khan

“Muscle–Organ Crosstalk: The Emerging Roles of Myokines”

Maintaining Muscle Mass & Organ/Brain Health

“Use it or lose it” is a common phrase that teaches us our bodies will not retain abilities unless we explicitly tell it to. This mindset could be applied to both the physical and mental aspects of our bodies. We must constantly challenge ourselves to remain youthful.

Hybrid Training

There is a growing community of athletes who are simultaneously able to powerlift at high levels and go run a marathon in the same day! While this example is quite extreme, hybrid training is proving itself to be a growing field.

We see in the diagram above that resistance training and cardiovascular exercise have different effects on our physiology. As a result, hybrid training would harness the combined benefits leading to better health outcomes!

Examples of Hybrid Athletes

Diet

In my last post I covered the idea of facultative carnivores and hunter-gatherer diets. Here are some of the mechanisms of how our bodies metabolize what we eat.

“The Top 20 Biggest Nutrition Myths”

Food Industry Corruption

Carbohydrates

Sugar consumption seems to be a complicated topic. Different foods have different glycemic index affecting spikes in blood sugar. However, I will discuss below whether this can affect individuals differently dependent on their athletic ability.

“Why The Glycemic Index Is Misleading“
(Lower GI foods are generally healthier, but this is not a catch-all)

Insulin resistance is the main concern of chronic high blood sugar. Elevated blood sugar levels over time can lead to metabolic dysfunction within our bodies. The resulting consequences can be wide and devastating (obesity, diabetes, heart disease, more), but what if you are an athlete?

Exercise is proven to be anti-inflammatory, increase insulin sensitivity, and create adaptations for efficient glycogenesis (uptake of glucose into the muscles).

Studies/meta-analyses still need to be done to determine whether high GI foods have negative effects on glycogen adapted athletes, but it appears it is an optimal fuel for endurance athletics.

“Effects of endurance exercise training on muscle glycogen accumulation in humans“ (Journal of Applied Physiology)

Both anaerobic (power) and aerobic (endurance) athletes seem to benefit from “carb loading,” where lots of glycogen is stored in the muscle. This creates a puffy muscle appearance, which bodybuilders love, but more importantly the fuel is stored and ready to go. Not to be confused with fat accumulation which has a different metabolism (this is what would happen if you carb load and you are not athletic/remain dormant).

Electrolytes

“LMNT’s electrolyte ratios explained”

Fats

I mentioned before that my favourite fats are EVOO, avocado oil, grass fed butter or fresh animal fats. The latest research proves that animal fats are in fact not unhealthy given you consume them appropriately. Survivalists understand the importance of animal fat for sustenance. In fact, in the recent season of “Alone” I watched how one competitor lost over 30 lbs despite having a whole moose to feed on. This was because a wild wolverine ate all the fat off his food and this loss of a vital macronutrient led to starvation.

Furthermore, cholesterol is a vital part of our diets. Testosterone is made from cholesterol as are many other hormones! Lots of conflicting advice is given about fats because of the clusterfuck that is the agricultural industry. Well here is the latest evidence based advice.

“The truth about fats: the good, the bad, and the in-between”
(Avoid the trans fats, limit the saturated fats, and replace with essential polyunsaturated fats) [Harvard Health Publishing, April 2022]

• Saturated fats are not bad
  (given good quality source, no overconsumption, active lifestyle)

• Trans fats are definitely bad

• Maintain optimal omega 3/6/9 ratios

  • Vegetable oils are high in omega 6/9 fatty acids

    

  • Diets should contain higher levels of omega 3 to offset modern foods
    ”Omega-6 to Omega-3 Ratio: What Does It Mean and What's Optimal?” (InsideTracker)

    

Adipose Accumulation

^ unless you have a diagnosed metabolic condition (get your bloodwork)

Our body fat is an integral part of our metabolism, but modern diets are much more caloric and rich than what our ancestors ate. This had led to a drastic rise in obesity, especially among Americans. In survival situations having fat accumuled is extremely advantageous as our fasting (low caloric condition) physiology are quite adept.

Multi-Day Fasting (Not Intermittent Fasting)

The powers of fasting are fascinating as a deeply rooted survival mechanism. It has been shown to promote a number of beneficial pathways, and autophagy in particular. This is the process in which our bodies repair our damaged cells, so effectively it is anti-cancer behaviour. I will expand upon this in my inflammation series (release date: TBD).

Keep in mind that fasting can result in muscle loss, but this is dependent on multiple factors such as your activity level and pre-existing level of body fat.

Sleep

Our brains produce metabolic waste just like any other part of our body. There is evidence to show that sleep is a process where we clear out this waste and consolidate memories/emotions. The science behind sleep is complex and we do not yet fully understand it. I will cover more about this topic in the future!

If you are interested, there are more videos about sleep in this post below.

How I optimize sleep:

- Early healthy dinner (5pm)

- Cold room (64 degrees)

- No caffeine after 12pm

- Go to bed early (9pm)

- No water after dinner

- Blacked out room

- Read before bed

- Track it (Oura)

- Sleep alone

- No alcohol

Skincare

If you’re gonna live longer, it’s probably a good idea to take care of your skin too. There are also other dangerous such as melanoma (skin cancer) from UV damage, particularly for those in exposure to the sun at elevated amounts. Whether it is occupation or recreational it is good to be UV aware.

“The Risk of Melanoma in Airline Pilots and Cabin Crew - A Meta-analysis”

A lot of sunscreens have questionable active ingredients and addities, especially chemical based ones. The best that I’ve found are non-nano zinc oxide sunscreens, however they do tend to have a white cast/pastiness. This seems to be the trade off for non-toxicity, which I think is an acceptable compromise.

Walking & Running

“These observations suggest that plantigrade foot posture improves the economy of walking. Relative to other mammals, humans are economical walkers, but not economical runners. Given the great distances hunter-gatherers travel, it is not surprising that humans retained a foot posture, inherited from our more arboreal great ape ancestors, that facilitates economical walking.”

“The influence of foot posture on the cost of transport in humans”

So basically heel striking is way more efficient for walking. However, there is a place for forefoot striking.

“Humans are very good at running long distances. We are physiologically and anatomically specialized for running long distances. But the anatomy of our feet is not consistent with economical running. Think of all the animals that are the best runners – gazelles, deer, horses, dogs – they all run on the ball of their feet or the tips of their toes.”

“The Cost of Being on Your Toes“ (University of Utah)

Nature tells us that running is most efficient on the balls or tips of your feet. Forefoot striking seems to be the best option when running.

“how to make sense of diverse arguments about minimal shoes, cushioning, and strike type? First, the restricted variation in strike type among habitually shod runners today may be a recent phenomenon, and it would be useful to test if runners adopt more variation when running on trails rather than on pavement or treadmills. In addition, although rearfoot and forefoot striking are both normal, everything involves trade-offs. RFS (rear foot strike) landings have the potential advantages of being comfortable in shoes or on soft surfaces, they require less calf and foot muscle strength, and they lessen external moments acting around the ankle [39]. Their potential disadvantages are that they cause impact peaks whose rate and magnitude are hypothesized by some researchers to be related to some repetitive stress injuries, they increase external moments around the knee, and certain kinematic patterns associated with (but not exclusive to) RFS gaits, such as overstriding and extended knees at landing, are implicated in some repetitive stress injuries [40]. More research is needed to evaluate the costs and benefits of different strike types, but one hypothesis that also needs to be explored is that running with more kinematic variation, as perhaps occurs during trail running, is more natural and may also be beneficial.”

“Variation in Foot Strike Patterns among Habitually Barefoot and Shod Runners in Kenya“

Heel striking and variations in foot strike seem to be natural to an extent, but this may only be beneficial on natural surfaces like in trail running.

Modern Hard Surfaces

Nowadays the surfaces we live on are a lot harder than what we encounter out in nature. From concrete sidewalks to indoor flooring we expose our feet to much harder surfaces in our modern society. Walking and running on concrete provides no cushioning, whereas we are naturally evolved to tread more responsive dirt surfaces.

If you are thinking of transitioning to more barefoot style movement it is a good idea to gradually transition to prevent injury, especially if you are older. Also, if you are always on concrete then having some cushioning is likely the better option.

“Foot bone marrow edema after a 10-wk transition to minimalist running shoes”

I think one thing to keep in mind is the drop of shoes. This can be advantageous during running as it puts you in a forward posture. However, this is not advantageous for walking or standing where it can put you in an unnatural posture.

Extra: Facultative Carnivores

This section of the post spills over into related topics in the upcoming weeks, but I thought the anthropological/biological relation tied in neatly.

“Digestive Systems - Herbivores, Omnivores, and Carnivores” (LibreTexts Biology)

“…the Latin term omnivore literally means “eater of everything”, omnivores cannot really eat everything that other animals eat. They can only eat things that are moderately easy to acquire while being moderately nutritious. For example, most omnivores cannot live by grazing…”

Hunter-Gatherer history

One interesting area to look at is the evolution of dogs alongside our hunter gatherer era. They were heavily integrated into our ancient societies and as a result shared the same foods as us. Dogs are in fact facultative carnivores, meaning that they are primarily carnivores that can additionally eat plant matter to satisfy their nutritional needs.

“Facultative carnivores are those that also eat non-animal food in addition to animal food. Note that there is no clear line that differentiates facultative carnivores from omnivores; dogs would be considered facultative carnivores.“ (LibreTexts Biology)

Preceding the agricultural revolution we mostly hunted animals with spears in large groups. Cultivated crop strains enabled farms to produce food yields beyond the natural amount, where before we could only forage here and there.

Another interesting thing to note is that anti-nutrients have been found to exist in plant foods. Plants do not have many mechanisms to defend themselves like animals so they employ chemical warfare, in the form of substances naturally occurring in their bodies.

“Are Anti-Nutrients Harmful?“ (Harvard School of Public Health)

“Is There Such a Thing as “Anti-Nutrients”? A Narrative Review of Perceived Problematic Plant Compounds”

Now “anti-nutrients” or phyto-chemicals are not all bad as it includes chemicals like terpenoids, tannins, polyphenols, and more. These have proven themselves to be anti-inflammatory, but we must still pay attention to each chemical case by case. For example, high oxalate consumption is known to contribute to kidney stones.

“Carnivore” Diet

Paul Saladino is the originator of the carnivore diet and I think there is some real merit to this idea. The simple facts are that the speed of plant cultivation outpaces dietary evolution. We see this in the agrarian malnutrition mentioned in part 1 of this series.

Now some people say that red meat causes cancer, but these findings below may suggest otherwise. It may just be about the cooking method and quality of the meat we consume. In fact, these reasons below may be the culprit behind the recent rise in colon cancer, even among young people.

“Nitrosamines in food raise a health concern“ (European Food Safety Authority)

• Nitrosamines (carcinogen) have been found in cured meat products, processed fish, cocoa, beer and other alcoholic beverages.

“Chemicals in Meat Cooked at High Temperatures and Cancer Risk“ (National Cancer Institute)

• Charcoal cooking/other high temperature cooking has been shown to form carcinogens: heterocyclic amines and polycyclic aromatic hydrocarbons (PAHs)

“What Does Science REALLY Say About Vegetable Oils and Cancer?” (UC Davis)

“Deep frying cooking oils promote the high risk of metastases in the breast-A critical review” (Food and Chemical Toxicology)

• Also, avoid industrialized seed oils (canola, other vegetable oils), the heat extraction process produces carcinogens: aldehydes, PAHs, and more.

• The main concern here seems to be about oxidation of oil. This is ideally avoided as much as possible. Oxidation can occur when oils are left exposed to air (oxygen) for extremely long periods of time (lack of airtight seal), kept heated for a decent amount of time (deep frying equipment) or heated over their smoke point and start to burn.

As you can see avocado oil and beef fat have the highest smoking points. Some refined oils have high smoking points, but of course the refining process may produce carcinogens. Other unrefined oils may have lower smoking points and they can be treated accordingly. For example, I do not sear or fry anything with my EVOO (extra virgin olive oil), I simply eat it fresh in recipes. In general, I think that fresh animal fats, grass fed butter, EVOO, and avocado oil are healthy. They are many studies showing positive cardiovascular effects. Margarine (refined vegetable oil with additives) is actually unhealthy and it is crazy how butter/animal fats were demonized by agricultural lobbyists.

Carnivore diet can include fruits, honey, and other whole foods. There is no reason to be dogmatic about it. This is probably very similar to what our ancestors ate: mostly hunted animals, some berries/fruits here and there, and other nutritious finds like honey, nut/seeds or vegetables/herbs/spices.

Nutrients critical for optimal human life found only in appreciable quantities/bioavailable forms in animal foods:

-Creatine

-Carnitine

-Anserine

-Taurine

-Vitamin A

-B12

-K2 (K2 in natto is from bacteria not soybeans)

-Riboflavin

-Biotin

-Iron

-Iodine

-Zinc

...

Nutrients optimal for human health found only in appreciable quantities in plant foods:

None*

*Some might argue vitamin C, which is, in fact found in animal organs and meat, and is also quite easy to obtain in fruit (which I think is great).

**Some might also argue that "phytochemicals," which is false. Many of these compounds are found in grass fed meat and organs.

***Fiber? Meh, you can get some from fruit if you want but I'm underwhelmed by it's value in the human diet.

*No I don't fear fructose. Please show me a single human trial with whole foods containing fructose that shows harm. I know of many that show benefit.

Soft Tissue Damage

In this post I will be talking about some of the other important tissues in our body aside from muscle fibers. When our muscles are damaged they can heal pretty rapidly, but this is not the same with cartilage or other connective tissues. This is why joint injuries can put athletes careers to a brutal end.

Things like our meniscus, bursa, labrums, intervertebral disks, and tendons are made up of these different connective tissues.

The main reason why it is hard for our bodies to repair our joints is because they are often avascular regions. This means that the low blood flow in these parts of our body slow our natural repair process.

Another problem with soft tissue repair is that our body can often utilize scarring instead of the full healing process. Tissue repair is a complex process that I will cover more in my inflammation series!

These injuries are also hard to diagnose because of the limited radiology options we have. X-ray & CT scan can only see bones. MRI is good but it still does not have the greatest resolution. Also, there are usually long wait times due to their limited availability/high cost. Ultrasound can work for more surface level tissues but again the resolution is limited, more-so than MRI. However, ultrasound is not as time consuming or expensive to set up.
