Introduction
This is a joint essay by me (Rob) and Hideaway, a contributor here and at other sites that discuss the human overshoot predicament.
Text in normal font is me speaking, and text in italics is Hideaway speaking.
Hideaway was the first to explain a new theory called CACTUS (Complexity Accelerated Collapse of a Thermodynamically Unsustainable System) that explains the conditions that must exist to sustain modernity, and why modernity will eventually end with a rapid collapse.
We discuss challenges associated with CACTUS and world events, and end with an emergency appeal by Hideaway to citizens of the world to force their leaders to attend a peace summit at Hideaway’s home in Australia.
Challenge 1: Modernity is Difficult to Understand
The big picture is that modern civilization behaves like a self-organizing energy dissipative structure.
Ask any AI to confirm this and you will get something back like:
The perspective that modern civilization functions as a self-organizing energy dissipative structure is a cornerstone of non-equilibrium thermodynamics and complex systems theory. This framework suggests that societies aren’t just collections of people and laws, but physical systems governed by the flow of energy.
Here is an analysis of how that comparison holds up under thermodynamic and systemic scrutiny:
1. The Thermodynamic Foundation
In physics, an energy dissipative structure (a concept pioneered by Ilya Prigogine) is a system that maintains its internal order by importing high-quality energy (low entropy) and exporting waste heat (high entropy).
- Biological Parallel: Just as a hurricane or a living cell must constantly “burn” energy to prevent falling into a state of equilibrium (death or stillness), a modern city requires a continuous, high-volume throughput of energy to maintain its infrastructure, transport, and digital networks.
- The Entropy Trade-off: Complexity is “paid for” by increasing the entropy of the surrounding environment. The more complex the civilization becomes, the faster it must dissipate energy to stay coherent.
2. Self-Organization and the “Maximum Power Principle”
Systems often organize themselves to maximize the rate of energy flow. This is known as the Maximum Power Principle (MPP).
- Feedback Loops: As civilization accesses denser energy sources (transitioning from wood to coal, then to oil and gas), it creates positive feedback loops. More energy allows for more specialized labor, which leads to better technology, which in turn allows for the extraction of even more energy.
- Emergent Complexity: No single person “designed” the global supply chain to look exactly as it does; it emerged as the most efficient way to dissipate available energy across the globe.
3. The Efficiency-Fragility Paradox
As these structures self-organize, they tend toward extreme optimization. While this makes them highly efficient at dissipating energy in a stable environment, it creates inherent risks:
- Tainter’s Complexity: Joseph Tainter argued that societies add layers of complexity to solve problems. Eventually, the energy cost of maintaining these layers yields “diminishing marginal returns.”
- Rigidity: To maximize throughput, “buffers” (like local food stores or spare parts) are removed in favor of “just-in-time” systems. This makes the dissipative structure highly sensitive to interruptions in the energy “feed.”
4. Metabolism and Scaling
Modern civilization exhibits Kleiber’s Law-like scaling, similar to biological organisms. Large cities, like large mammals, actually become more “energy efficient” per capita as they grow, but their total energy appetite never stops increasing. If the energy supply plateaus or declines, the “metabolism” of the structure cannot be maintained, often leading to a forced “simplification” or collapse to a lower state of complexity.
Comparison Summary
Feature Dissipative Structure (e.g., a Storm) Modern Civilization Requirement Constant energy gradient Constant fuel/electricity input Organization Spontaneous/Emergent Market-driven/Technological Waste Heat and turbulence Pollution and low-grade heat Endpoint Dissipates when gradient fails Simplifies when EROEI drops This lens effectively moves the conversation from political or economic theory into the realm of biophysical economics, where the physical laws of thermodynamics set the hard boundaries for growth and stability.
Would you like to explore how the Energy Return on Investment (EROEI) of different fuel sources acts as the “pressure” that drives this self-organization?
God dammit, I asked you for a yes or no answer.
The short answer is yes.
From a biophysical and thermodynamic perspective, modern civilization functions exactly like a self-organizing energy dissipative structure. It survives by importing high-quality energy, using it to maintain its complex internal order, and then exporting the resulting waste as high-entropy heat and pollution.
Why the answer is “Yes”:
- Thermodynamic Necessity: Like a hurricane or a biological cell, if you cut off the energy gradient (the “fuel”), the structure cannot maintain its complexity and will spontaneously simplify or collapse.
- The Maximum Power Principle: Civilization doesn’t just use energy; it self-organizes to maximize the rate at which it dissipates available energy to expand its boundaries and technology.
- Metabolic Scaling: Large-scale urban and industrial systems mirror biological organisms in how they consume resources and generate “waste heat” to stay far from equilibrium.
Essentially, “money” and “economics” are just the human-layer interfaces for what is, at its core, a massive physical engine governed by the laws of thermodynamics.
Why did I subject you to that AI slop?
Because when you strip out the hubris it is the governing force behind what’s going on in the Middle East right now.
Our leaders sense via growing debt, slowing growth, worrying energy forecasts, growing inequality, falling living standards, and rising social unrest that the energy gradient that sustains their countries is falling.
Some leaders have decided to capture by force a bigger portion of remaining resources for their countries.
Unfortunately, our leaders do not understand CACTUS which explains that the non-renewable energy and material flows that sustain modernity must grow, which requires the complexity of extraction technologies to increase, to compensate for falling reserve quality as non-renewable resources deplete, which requires a complex 6 continent supply chain, with contributions and cooperation of all countries to function.
CACTUS warns us that stronger countries taking by force resources from weaker countries will damage fragile networked hyper-optimized global supply chains, which will prematurely collapse modernity for all countries, including the stronger countries.
Challenge 2: CACTUS is Difficult to Accept
The ideas of CACTUS are difficult to accept for several reasons.
Our education system and culture teaches that humans have agency over their destiny and therefore political, economic, and personal choices control the destination. Most people believe that innovation, determination, and faith can fix any problem.
Political, economic, and personal choices do indeed influence the rate of growth, the maximum altitude, and the duration modernity exists, however modernity’s dependence on many depleting non-renewable resources guarantees a destination without modernity, no matter what we do. We do however have some control over how long modernity will last.
CACTUS is difficult for most people to accept including:
- citizens taught that innovation, determination, and faith can overcome any challenge;
- leaders that must believe in and promise a bigger better future to be elected;
- overshoot aware activists working to retain modernity and steer civilization towards a sustainable path via green growth, circular economy, steady state economy, degrowth, population reduction, regenerative agriculture, fusion energy, or colonizing Mars.
I, for example, believed for over ten years that if somehow a way could be found to break through our genetic tendency to deny unpleasant realities as explained by Dr. Ajit Varki’s MORT theory, so that a majority of citizens became aware of our (very unpleasant) overshoot predicament, then we could return to a sustainable path and retain some of modernity’s best elements via rapid population reduction policies.
After Hideaway introduced me to CACTUS I resisted accepting that it was true for about a year because it forced me to accept that population growth is a prerequisite for modernity, because the complexity of extraction technologies must grow to sustain flows of non-renewable resources as the quality of their reserves declines, and growing populations are necessary to make advanced technology feasible and economic.
I did not want to believe that population growth is a core requirement for modernity because I had spent over 10 years learning that over-population was the core problem behind almost all of our problems. I wanted to believe a small modernity in balance with other life on the planet was possible.
I did not want to believe that modernity would collapse very quickly in months or years, rather than following a slow decline providing time to adjust over decades or centuries as most overshoot aware people assume.
I understand the human genetic tendency to deny unpleasant realities. Imagine how hard it must be for someone unfamiliar with MORT to accept CACTUS.
The evidence speaks for itself. Almost all of the most talented and famous overshoot intellectuals of the the last 50 years missed CACTUS. The only place on the planet discussing CACTUS is the tiny community of nobodies that frequent un-Denial. We have been unsuccessful to date getting any influential person in the overshoot space to even mention the word CACTUS.
Ditto pretty much for MORT.
Challenge 3: Risks Just Exploded
We are in the late stages of an advanced civilization. Growth has slowed or stopped, there are no new big reserves of high quality resources available to restart growth, and many frictions are building like war, debt, inequality, birthrate, pollution, climate change, and ecosystem loss.
Most of the people who understand our predicament thought we had anywhere from 4 years to a maybe a decade or two before the inevitable decline of modernity began. That meant we had some time to, in a best case, influence society to prepare a softer landing zone, or in a worst case, prepare personally, for the loss of modernity.
The US attack on Iran 23 days ago changed the forecast to a possible worst case scenario of modernity collapsing this year, and because of our recent CACTUS learnings, a total loss of modernity could occur very quickly once the collapse begins.
Ask your favorite AI, “how long can Hormuz remain closed before the global economy collapses?”.
You will get an answer of about 3 months based on energy reserves held by some countries, energy stored in ships in transit, and fertilizer shortages causing a food crisis.
Now ask your AI, “what duration from peace agreement to resumption of normal Hormuz operations did you assume?”.
You should get an answer of about 4-6 weeks based on time to clear the mines, restoration of insurance, and restarting logistics.
My sense is that 4-6 weeks is wildly optimistic to restart a global system of this complexity.
Infrastructure has been damaged, wells have been shut in and possibly damaged because storage tanks are full, bunker fuel is scarce and expensive, 3200 ships and 20,000 mariners have been trapped in the gulf that need to be reprovisioned and rescheduled, there’s a high probability a serious recession will begin shortly making it difficult for customers to pay for higher priced energy, and it will take time for trust and order to return.
One expert retired merchant mariner predicts at least 30 weeks to restart Hormuz after 30 days of closure.
Now ask your AI to revise its estimate assuming it takes 30 weeks to restart Hormuz operations.
It will answer that all material buffers in the global economy will deplete and the global economy will collapse before the end of 2026.
Then go back and think about what CACTUS implies and how hard it will be to restart modernity after the complexity that sustains the material and energy flows needed for modernity collapses.
You will conclude that even in a best case scenario, we may already be in big trouble.

Now consider President Trump’s ultimatum to destroy Iran’s critical infrastructure if it does not reopen Hormuz in about 12 hours from now.
Then consider Iran’s reply that it will respond by destroying critical energy extraction infrastructure in other gulf countries. Also consider Iran’s track record over the last year of doing exactly what it said it would do.
If Trump follows through on his threat, a best case that already threatens modernity this year, becomes a worst case too horrible to imagine.
Challenge 4: Hideaway’s Viral Peace Summit
If leaders understood CACTUS they would not be doing what they’re doing.
If citizens understood CACTUS they would force their leaders to also understand CACTUS.
Wars over depleting non-renewable resources, between modern countries dependent on the growing complexity and scale of a hyper-complex networked 6 continent supply chain to sustain them, will not result in a few wealthy victors and many poor losers, rather, wars will shorten the time to collapse of modernity for all countries.
Hideaway, in a moment of lucidity and boldness induced by the combination of prescribed ketamine, and Trump’s dangerous ultimatum, issued a challenge from his hospital bed to all citizens of the world to force their leaders to attend a peace summit at Hideaway’s home in Australia, where he will explain to them how the world actually works, the CACTUS implications of their decisions, and choices that would actually work to extend modernity.
As the price of the spice of all of our lives (oil) goes higher, standing in the back stalls looking at the big picture, our entire super complex system of civilization, is an energy dissipative structure, that runs on an ever increasing amount of energy.
The leaders, that we have chosen to represent us, or have allowed to flow to the top, think it’s a good idea to put it all at jeopardy, over a difference of opinion on how to end civilization, do it now seems like their preferred option, or they could come to some type of peace agreement and wait a bit longer for collapse to get us all.
It’s their decision..
They could all ask their top physicists what less energy will do to their own people, but they wont do that, they are more concerned about the ‘others’, having less than themselves (sorry their people).
They will possibly never consider sharing equally like humans did for 99% of our time of existence on this planet, as that would be inconvenient to their supporters.
The MPP and boundaries are the problem. Lines drawn on maps, you’re either us or them, why ??
Why because us leaders said so.. They are bad, we are good, so we need a line to separate our bit (my bit).
Sorry, I use to know them, they were good people, how did they become bad people?
They live on the wrong side of the line, look their hair is different, their skin is changing colour, they pray to the wrong gods, they are devils, evil.
FFS enough of that everyone gets the picture, we are all led into beliefs of one sort or another, and now we have it at an international scale that can end civilization, if they so chose.
I will bet my last can of sardines, (hang on, I have to save one to send to Rob in a couple of days)… that none of the leaders in this conflict of brinkmanship has all the details or all the answers, and is floundering just like the rest of us.
I put a challenge to the leaders of this conflict, I dare you all to come and meet me, bring your families and best friends, sit down and have a chat about getting rid of boundaries and restrictions on ‘others’ so we can all increase entropy together, instead of fighting over the last resources of the planet.
Then, if there is no agreement, blow it all up, with the first nukes headed towards where we all sit…
I bet my next to last can of sardines, that none will take up that sort of challenge, or anything similar.
Civilization is no different to an animal body, a small choke point on an essential artery, can kill billions of separate cells, because that one blockage stops the rest from working together as intended, and death.
We have a choke point on our civilization called the Strait of Hormuz, we can chose to close it, or to keep it open and keep billions alive now, to die later rather than earlier, your choice…
As stupid as it all sounds, we have a choice of collapse now or later, the headlines I’m reading are suggesting the decision of the leaders is to collapse now instead of later.
The power of the internet, simple words, on a screen, is unlike anything humanity has ever had before, and no-one really understands the power of people power if enough get the message.
My message is simple, stand outside the house of a politician, any politician, and demand they choose peace, not violence and death, and go to my home in Colac.
If the message becomes viral, then people will start doing it, in every country of the world. All the intelligence services have enough smarts to work out who we are and where we are, they can come to us.
We have all the tools at our disposal, to get to just about everyone on the entire planet, in a single short period of time, if people want to choose peace instead of death and violence.
We only need one of the leaders to actually get the message, the rest will follow. So it’s the current big 5 at the centre of this, DT, Vlad, Xi, Bibi and Mojtaba.
We’re in a new world of our own making and none of us have control, but we can try and do our own little bit. I’ve seen no solutions offered anywhere, I have a few that will work, if those involved are willing to come and talk to me, in the name of peace. No-one will really like them, but the alternative is, end it all now..
If that lot are desperate for a solution, come and have a chat altogether. If fighting is the only answer, then the first bomb goes off here, at the peace talks, and new more sensible leaders can come up the ranks.
I have a hope there is a 0.1% chance that leaders will grab at any solution as they all know the consequences of the current line they are taking. Am I a madman, possibly, if de-escalation is considered mad…
And thanks for all the fish…
