Only this is on a microscopic level where eventually, particles, through probability, find _their_ configurations that disperse energy (settling where they "want" to be per thermodynamics) and in the process form more bonds among the particles. Maybe a tiny human diving in to that microcosmos might have found that annoying too!
Who would've known, annoying bunched up cords and wires might have carried a hint to bunched up complex molecules and genesis itself!
The article says it "underlies rather than replaces" Darwinian evolution but I'm not sure that's necessarily the case. Sure general relativity "underlies rather than replaces" Newtonian gravity, but honestly, the understanding of GR gravity does "replace" a pure Newtonian understanding.
Darwinian evolution focuses on survival pressures to force natural selection. An entropic basis for evolution can explain things other than survival pressures; evolution can occur on a basis that rather than "improving survivability" it simply is a more functional expression of entropic drive.
How would this change how how we view evolution? It would be massive and perhaps explain a lot of the oddities in the evolution of very complex features where full functionality and marked increase in survivability is very delayed...
Would love to see further research along these lines
Summary. A simple statistical model is constructed, describing the transition from disorder to order in a population of mutually catalytic molecules undergoing random mutations. The consequences of the model are calculated, and its possible relevance to the problem of the origin of life is discussed. The main conclusion of the analysis is that the model allows populations of several thousand molecular units to make the transition from disorder to order with reasonable probability.
I got on to this from the bit of his Web of Stories interview talking about it [2]. I listened to the whole interview recently, and highly recommend it.

* Life "obviously" evolves where heat/energy is isolated into packets at some (many) levels * What is the F's 3 gear problem with respect to life? * The origin of life as a heat-management problem, with time-reversibility, sensu the video. * Life evolves in some time-reversible (mostly isolated) system that allows energy back and forth, a "DNA molecule" separating, and joing back, and separating, and joining back (until there is a little moment of chaos, and it doesn't separate, or come back, because the process is interrupted), at this point systems that can manage heat, i.e. shunt energy packets away, can prevent "mutations", at just the right time, so that they continue to go back and forth, separate the DNA, bring it back (time reversable). * "Shunting energy away" -> moving chaos to another place * Life is irreversible, therefor it must be a "machine" that shunts energy away * In as much as the collective Earth/Gaia "learns" to shunt energy away, then it will become collectively "alive" * We are at the point where we need to shunt Energy away, therefor the Earth is "Alive" * The earth / heat - at some point the finned shaft sensu F has to break through to space, to let the heat "out" * Why are trees? Yes this is a complete sentence. I.e. if there is some "fractalness"/"modularity" to earth, then this heat managing problem should repeat at many different levels. What are the "cold" counterparts to trees? If the gear is a tree, then what is the "fin"? How does the tree gear energy move back to the fin?
Because the idea the article presents is that if you have matter that is being bombarded with energy (e.g. electromagnetic radiation) and is in an environment where it can dissipate heat (like the ocean), that this leads to self-organization of that matter to more efficiently convert the energy to dissipated heat, and that this could explain the early evolution of life.
Key quote:
> "Particles tend to dissipate more energy when they resonate with a driving force, or move in the direction it is pushing them, and they are more likely to move in that direction than any other at any given moment. This means clumps of atoms surrounded by a bath at some temperature, like the atmosphere or the ocean, should tend over time to arrange themselves to resonate better and better with the sources of mechanical, electromagnetic or chemical work in their environments,” England explained.
But there's zero explanation of why. It's not like the matter has some goal of dissipating the energy or becoming resonant in order to do so. It seems far more likely that the matter just absorbs or reflects or transmits the energy, and that it heats up to the extent that it absorbs it (and maybe melts a bit or something, e.g. becomes even less structured). But I don't understand what principle would lead the matter to become "resonant" or structure itself to "more efficiently" absorb and dissipate the energy. Clumps of atoms don't care, do they?
It's like the article is relying on some new physical principle of "desire to dissipate energy efficiently" in non-living matter but without naming or justifying it. Can someone else point out what that principle might be, or if there is one at all? I've gone through all the links in previous submissions and can't find any mention of it. Or am I misunderstanding or missing something here?
It says that England made more meaningful contributions to the biological aspect.
That's in the paper, not the article. The rest of the article is physicists making ill-informed statements about biology they don't understand. The conceptual model isn't novel, it's rather standard to students of evolution and entropy. But the specific concrete mathematical-physical model of how light becomes life is incredibly important, but up to the experts to validate and product in experiment.

TLDR: the universe's telos is entropy increase, and thus its emergent structures like life, intelligence, and capitalism favor entropic acceleration
It is not clear to me from the article, however, that this theory goes so far as to explain the latter, either. It seems to be saying that if you take something like what we believe the primordial earth was like, then one might expect life to emerge, but it does not seem to have suggested specific processes leading to that outcome.
Nor does the article give any example of how it has led to a satisfactory non-Darwinian explanation of an allegedly problematic case of evolution. If that has changed since the article's publication in 2014, I would be very interested in hearing about it.
I don't see why it would have to lead to a non-Darwinian explanation of evolution. As has been said by in the parent comment, survivability might just be a high-level manifestation of entropic drive of self-replicating systems. It's remarkable that this is a claim that can be falsified, whereas Darwinian evolution, well..
> I am just saying that from the perspective of the physics, you might call Darwinian evolution a special case of a more general phenomenon.
I think this is exactly alligned with your Newtonian-GR analogy.
Entropy (according to Boltzmann) is proportional to the number of microstates that can give rise to a particular macrostate of a system. The macrostate with the highest number of possible microstates is the uniform one, where all the accessible microstates are equally likely. So if by the 2nd law entropy must increase, the system will tend towards the uniform configuration.
In other words, if a force is pushing water, the configuration with the highest number of states is that where all the particles of water are also moving i.e. indistinguishable microstates, doesn't matter how you rearrange the moleculles, it will look the same as they are all moving uniformly. It would be extremely unlikely that there were a pocket of water that is mysteriously still in the middle of the stream no? Clearly there are not a lot of rearrangements of the mollecules that will keep the macrostate the same, so low entropy, which tends not to be the case.
(Edit) How this connects to the "desire to dissipate energy efficiently":
Essentially, when we talk about "energy" we really mean "free energy". This is the amount of work that we can extract from a system. This is nothing but a measure of how far a current system is to it's maximum entropy state. So dissipating energy = increasing entropy.
The mindblowing part for me is the connection that the process of extracting free energy is the same process that moves a system to its most likely state, uniformity, high entropy. So somehow, the ability to _accelerate_ an already inevitable process lets us reconfigure other systems _away_ from their most likely state!! So if we imagine the arrow of time to progress at the average rate of entropic decay, we are essentially reversing it for some systems by accelerating it for others!!!
Man...
> So somehow, the ability to _accelerate_ an already inevitable process lets us reconfigure other systems _away_ from their most likely state
But this is exactly the part that doesn't make sense to me. Why would it accelerate? There's no principle I'm aware of that would prefer or cause this accelerated version. There's no such "ability".
Rather, the entropy process just happens in this "already inevitable" way you describe, without any self-organizing "resonant" structures or anything or the sort. I don't understand what would cause anything different.
It's kind of like saying boulders eventually roll downhill, so therefore hills spontaneously turn their rocky surfaces into smooth slides so the boulders can roll down faster. But that's not how it works.
Doesn't it, though? Everything is thought to be tending towards higher entropy, and the dissipation of heat helps accomplish that.
There's no reason I can see why atoms would spontaneously rearrange to try to help that along in their local spot. It's not something that needs any help. Entropy increases, but there's no law that says it always increases as quickly as possible, as soon as possible. It just happens as physics describes it.
> The overarching goal for humanity is to preserve the light of consciousness.
If all physical processes are subservient to a thermodynamical "telos", how could any manifestation of free will emerge? Not even going to get into how problematic it is to cite conciousess as a fundamental goal of when we cannot even assess its existence in other beings.
> Technology and market forces (technocapital) are accelerating in their power and abilities. This force cannot be stopped.
What? Cannot be stoped? How could humanity possibly play any role in an unstoppable process? Surely no one can deny capitalism to be the result of specific choices in human history? Hence why we can concieve alternatives to capitalism and can very well choose them over capitalism.
> Technocapital can usher in the next evolution of consciousness, creating unthinkable next-generation lifeforms and silicon-based awareness.
Can? How could it not if the claim is that it's unstoppable? Concisouness again?
> HUMANS HAVE AGENCY RIGHT NOW. WE CAN AFFECT THE ADVENT OF THE INFLECTION IN THIS PROCESS
Scratches head...
I would love to have a rigorous debate about some of these ideas but come on... I was recently in an X space with some of the writers of this manifesto and was very disappointed.
Agreed, this is a point which I don't think is empirically backed as rigorously as the rest of e/acc. Consciousness preservation is a side effect of the currently most successful form of life (humans) also evidently having consciousness.
> What? Cannot be stoped? How could humanity possibly play any role in an unstoppable process?
I take issue with the claim of "cannot be stopped". Certainly the extinction of humanity would result in capitalistic acceleration ceasing. But we'd simply be knocked a few levels down the emergence ladder. Darwinistic acceleration would continue to proceed on a biological level, eventually begetting a species with the ability to accelerate on shorter time-scales (intelligence) and across larger spatial scales (culture). I'd say that humanity doesn't play a role, but is rather an instrument of this acceleration process.
> Surely no one can deny capitalism to be the result of specific choices in human history? Hence why we can concieve alternatives to capitalism and can very well choose them over capitalism.
I don't think capitalism is necessarily the global maximum of economic systems for thermodynamic acceleration, but it is certainly the most effective system in existence at the moment. We can conceive of alternatives, but if a subset of humans were to choose them, historical precedent suggests that they would be out-accelerated by capitalism.
> Can? How could it not if the claim is that it's unstoppable? Concisouness again?
Given long enough time, it will. But it might need multiple reboots and bumps down the emergence ladder if we fuck up.
You do bring up some great points about agency vs instrumentality that I'd like to think longer about though.
Its a bit unrelated, but I don't think your statement about capitalism being a result of human choices is correct. Capitalism is the emergent property of a multi agent resource collection game where one's resources compound in proportion to their quantity. Its the outcome when agents don't co-operate.
The best quality of life features of modern society, such as human rights and safety standards, only emerged due to coordination working against the forces of capitalism.
In a Universe that favors capitalism, you would think there would be plenty of evidence of a few entities exploiting the rest to drive entropy maximization. Instead what we see is that life is scarce, so scarce that we can't even be sure that there is other life in the Universe. Where are the Universe's capitalistic overlords who can make us pee in bottles lest we waste precious time maximizing entropy generation?
Consider an active entity with a finite lifetime (e.g. child, factory). A production function can be defined as the net balance of flows in/out of the entity. This could be resources, energy, money.
As time progresses after t=0 (pregnancy, project plan), the production curve starts off negative (even a self-employed craftsman has to buy tools), perhaps it dips more negative (debt, nurture/education).
Eventually the curve slopes upward and crosses the breakeven point. Growth slows, the curve reaches a maximum positive value, then falls asymptotically toward zero, maybe going a little negative, before being truncated (death, scrap - even funerals and demolition cost money).
The net contribution is the area under the curve.
Resources have to be invested before there can be any benefit. The fact of any final net positive contribution is uncertain at the outset.
> when a group of atoms is driven by an external source of energy (…) and surrounded by a heat bath (…), it will often gradually restructure itself in order to dissipate increasingly more energy.
To be honest I cannot go any deeper without reading the paper.
Is that part of what these new theories are arguing though, where they are claiming that the universe does behave that way? Or is it this game where under certain conditions, molecules begin to self-assemble and thus decrease the local entropy but then must do so in a way to account for that and increase the local entropy (implying efficient heat dissipation), hence life?
Cooperation is a choice, as you very well say immediately below the above statement.
The cause "given enough time" seems to leave the questions of how probable it is, and how widespread a phenomenon it would be, wide open.
> I don't see why it would have to lead to a non-Darwinian explanation of evolution.
To be clear, I don't think it does, and I don't read galenmarchetti as going that far, either.
> It's remarkable that this [survivability might just be a high-level manifestation of entropic drive of self-replicating systems] is a claim that can be falsified.
Can it be falsified? It seems a rather broad claim, and it is unclear to me that the falsification of England's theory would rule out some other theory succeeding.
Could it be falsified? I think if you could show that natural selection led to the survival of less dissipative life forms then you could claim falsification.
