đ€ Musings On Cargo Cult Consciousness
Like many of us, I once dreamt Iâd live long enough to upload my mindâone Planck at a timeâto live happily ever after in a digital heaven. This is a dream now dead. Crushed in a head on collision with logic and reason, its twisted wreck revealed a nightmare that threatens all future mind. So in its wake, my misery and I invite you on this same journey, we could certainly use the company.
Before setting off, I should probably point out a few things:
- Thereâs a lot of hyperbolic argument and weak analogy in this article, and it comes across as combative. I could be more agreeable, but thatâs not me, Iâm having fun. It does have a purpose. Its intended function is to sew irritations that become dissonances later. Revisit after a few sleeps if you can stomach it.
- The historical position and criticism of mathematical thinking arenât meant to be an attack on science or rationality, their function is to show weaknesses and biases that we must understand in order to overcome.
- The central points are around the best leap from solipsism and the facts of biological evolution. The conclusions that follow are less developed but from what I can see, they do follow.
With that out of the way, letâs go. What would make my dream believable in the first place? Why would I think it possible that software could have conscious experience? Is this a position reached from first principles when guided by reason, or from assumptions and led by bias? Is there an angle that can reveal the shape of our own lens, or the scent of our cultural ether? The direction I chose was to look from the past, from our history.
âȘ A Meek Inheritance
We modern people owe many of our values to Western science, we have a great respect for its ways of thinking and proudly identity with them. We tend to forget that many of them are Christian, that its story is one of Christians. Its story starts when Gutenbergâs bible machine brings the words of Catholic Humanists and astronomers to Locke, whoâs writings posthumously inspire other meek and humble souls to become closer to God by probing His Creation, learning His Laws and thereby knowing His Plan. Among their ranks are all the greats; Galileo, Hobbes, Boyle, Newton, Leibniz, Priestley, Faraday, Darwin, Mendel, Pasteur, Maxwell, Tesla, Planck, Curie, Bohr, Heisenberg. Their Deist, Jewish and other peers shared many of the same fundamental beliefs, as did most philosophers and mathematicians who shaped our cultural heritage. You could argue some were more agnostic, but they largely prayed and went to church, the ether of their belief systems was Judeo-Christian.
Their worldview starts off something like this:
Reality consists of two realms, the first spiritual and the second physical. They were created for us by an all seeing, all knowing being of infinite power, who made us in His image. As the decider of right and wrong, moral authority comes from those who know and obey Him. Our souls are immaterial and eternal, tethered to our bodies for the duration of our lives, and will face His judgement upon death.
The sands of time and air of change wear this away, add to it and leave us with something more like this:
Moral authority is held by those with most knowledge of the world. All that cannot be proven empirically should not be believed. Existence consists of matter and energy that obeys mathematical Laws of Nature. There is no spirit realm, only the physical. Space and time extend infinitely from a starting point that may also be infinite. We emerged as the result of Natural Law.
This seems fine until you consider that it wasnât built from the ground up using rational methods, itâs the evolution of Judeo-Christian ideas sharing a meme pool with rationality. A cynical and hyperbolic look at its vestigial limbs and appendicitis risk might look something like this:
- Moral authority is held by the learned
- Objective reality is Truth
- All things obey Mathematical Law
- We were created by Its Law
- Mathematical structure gives rise to mind
Iâm being pretty uncharitable here, but the point is that not much has changed. We have a new clergy and even kept the dichotomy of good and evil, we lost the law giver but not the concept of obedience to his laws. A mathemystical ruler replaces the almighty, the spiritual realm and the giver of souls.
đ Mathematical Mecca to Materialism
From Descartesâs position that we can only prove that we exist, itâs true that everything else might be a dream. Any path of pure reason leads to a dead end of solipsism because he was right, we canât say anything about anything else. So unless weâre going to take the selfish stance that everything is only in our heads then we need to assume something with no proof at all; we need to take a leap of faith. The most popular leap today is to physicalism, thatâs the assumption that everything that exists is physical stuff following the laws of physics, itâs a refined and trendier name for stale old materialism. The reason we choose this unprovable assumption over others is historical.
History had proven it unwise to trespass on the politics, pyres and pokers of the church, and so the men of science kept a safe distance from matters of the soul - of the mind - and focused their efforts on Godâs creation. The tools they used were sharp, and through centuries of inquiry the need for a creator was reduced, and each discovery pushed Him further into the gaps.
Heliocentrism, then geology, evolution and finally the big bang refuted the creation story, while the other disciplines eroded everything else. Disease, weather, natural disasters, the nature of people and even how best to run society - they all eventually became the property of science. The pursuit of knowledge slowly ground Christianityâs once unquestionable truths to dust.
From this storyâs narrow focus, Occamâs razor did the most damage. This ancient (and wholly Christian) tool of thought is thinking that goes like this âthe most likely explanation for a thing is the one with the fewest assumptions, so to find the true reasons for things we ought to shave away as many as possible.â And so the creator was cut away as unnecessary to explain the creation, and His two realms of existence were shown to be an obvious one too many. But because the ones wielding the blade were authorities of the physical realm, they sliced away the spiritual.
This left us with a problem. The only thing we truly know to exist is something that we donât believe in, while the things we know lots about canât actually be shown to exist. Empiricism has perfectly modelled our dream of the world, but it has said nothing about we dreamers. This problem underpins âthe hard problem of consciousnessâ, the question of why we, as dumb matter, experience anything at all rather than nothing, like everything else.
Attempts to fix this are off-putting to laypeople, having the unfashionable odours of either the supernatural or of philosophical language; Panpsychism reeks of spiritualist woo, process philosophy is wordy guff.
So another, much more worthy air sits upon the throne, one both clever and known to get results. Her name is Mathematics. In the rule of maths computationalism is orthodoxy; consciousness caused by mathematical complexity is respectable. If itâs too confusing then itâs a familiar confusion, everyone knows that maths is hard. It takes knowledge and intellect to know, just like physics, chemistry, or any of the other fine institutions built by our best and brightest, and mathematics underpins them all. So mathemysticism fits snugly into this gap left by an eternal, all-powerful, almighty giver of laws, and a post-Him world clings to His law.
This opens up a nice detour to plough through mathematics.
â Infinitely Nothing
I could go into another ramble about how Cantor baked the infinite glory of God into the core of modern maths in a way that Newton didnât dare, but Iâm sure youâve heard enough about that. Keep in mind that without infinity thereâs no everafter, no omniscience, no omnipotence, no infinite wisdom and grace. People are comfortable with the lack of an Eternal, but tend to believe in infinities, despite the fact theyâre either too large or too small for anyone to see.
As for the small, so far as we can tell, there was a start to the universe and there will be a point in time when all will have dispersed wide enough that it canât interact; in practical terms time and space are finite. Thereâs also, so far as we know, a smallest possible distance in both, to the point where any point in spacetime could be referenced by a 1kb address. Thoughts of any kind of spacetime continuum should be off the menu until a delivery of fresh evidence arrives, after all, infinite claims require infinite evidence.
From a crude lay-hacker perspective, infinity seems like one of those ugly errors that piss out all over your runtime when your abstractions leak. What is it though? Letâs do a poor manâs Russell, and start off with one bunch of things we want to group with another, we call that process addition in order to model it. To do the inverse we call that subtraction, but inverse operations are a pain, itâs usually harder to undo something than it is to do it. Rather than put conditions on subtraction, we could have ways to carry the errors and recover from them later, so we have the invention of 0 and negative numbers. Itâs not like you can actually have zero or minus one apples, theyâre hacks that exist one abstraction level away from the model of things. Multiplication is just repeated addition, but now we need special cases for 0 and for negatives, so we bolt on rules around those. Division, repeated subtraction, has those plus another error when combined with zero - you get infinity. Exponentials need more workarounds, and their inverse gives us an imaginary yet useful toe-stubber. These tools work well for exploring patterns, theyâve been shaped that way through usage, but itâs easy to forget that zeros, negatives, infinities and imaginaries are artefacts of a system we use to explore relationships between things, they do not need to refer to things themselves; like all of mathematics they are maps, not territories.
Similarly, randomly pick a number from the set of natural numbers, the positive integers, and you will never pick one thatâs short enough to be written down. Thereâs an infinity to 1 chance that the stars wonât burn out before you could. The natural numbers are unnatural and canât exist, and as for the reals, having an infinity on both sides of the decimal place makes them infinitely less real. The same can be said of infinite series, itâs useful to think of rotations as an infinite vibration between squares and powers, but why attribute rotation to an infinite loop when 50 are more than youâd ever need in our universe? Practicality is ignored in the quest for purity.
This attack on infinities and continuums isnât just because they havenât earned their keep, itâs to cut the legs off of Hofstadterâs Strange Loops.
đ Strange Hoop Jumping
Emergence is the idea that behaviours at a smaller scale lead to ones at a larger scale. Repeatedly step forward and turn one degree to the right, a clockwise circle emerges. Pressure is an emergent property of gas particles bouncing around, sound waves and wind emerge from pressure changes. This sort of emergence is well understood and is definitely a thing, but thereâs a second type of emergence thatâs postulated by mathemysticism: strong emergence.
Strong emergence is the idea that a new fundamental property can emerge from a system, a new type of thing that canât be explained by the systemâs rules at the level below. That property is, of course, consciousness - itâs the only thing that is believed to emerge strongly. The dominant âbecause complexityâ position among comp.sci people is Hofstadterâs Strange Loops. This explanation of consciousness is that mind mathemagically emerges from infinitely self-referencing, recursive contradictions. This is incredibly hard to grasp, and while such loops might exist to some degree, thereâs no reason theyâd cause internal experience. It seems to me a theory where descriptions of things are confused with the things themselves; one where maps masquerade as territory. A model of modelled models its a true emergentâs emergence, and âthe map is not the territoryâ ought to apply the emergency brakes; it yields a contradiction when combined with its mantra.
If we look at what can emerge from lower levels to higher ones, without deliberate strawmen but not nearly enough rigour, it looks a bit like this:
Lower level | Higher level | Outcome |
---|---|---|
Determinism | Free Will | Free will is an illusion |
Matter | Mind | The mind is a mere side effect |
Objective reality | Subjective experience | A type of conceptual framing, an infinite number of which are valid |
If we start the other way round, a different picture emerges:
Lower level | Higher level | Outcome |
---|---|---|
Free Will | Determinism | Determinism emerges from tightly constrained choice |
Mind | Matter | Matter emerges, itâs just mind stuff stuck in predictable patterns |
Subjective Experience | Objective reality | A type of conceptual framing, a useful construct that doesnât exist |
So thatâs why Iâm going to argue for the latter.
Panpsychism
Earlier I said that for practical reasons alone, we have to take a leap of faith that other things actually exist. Having âmind stuffâ and âmatter stuffâ doesnât make sense without assuming God created separate heaven and earths, so whatâs a good leap to make?
If weâre to make an assumption about what other stuff is like, thinking about what weâre like is the only starting point that we have. Itâs pretty fair to go from âI think, therefore I know I must existâ to âif other people exist, they probably think too.â A larger step that way, it looks like people are made of ordinary stuff, so by extension other stuff is itself likely to be at least a bit like that, though much simpler. What else am I? Iâm in a location, I experience my surroundings and the passage of time, I feel, and I choose how to move; I have will, agency. So I think that any rational metaphysical stance ought to default to a subjective over objective reality, ought to be local rather than global, be causal, and both experience and choice should be the default rather than illusions or side effects. Deviations from these need explanations that actually work.
Thatâs how Iâm justifying a panpsychist leap of faith. Iâm assuming that everything feels like something, and it chooses what to do based on how it feels. So there is no âobjective realityâ or âphysical realmâ, matter is just things interacting with each other. To quote (the great, late[^1]?) Budnik âsubjective experience is the totally of existenceâ, but with the addition of choice and removal of maths as its core. Think something like Whiteheadâs congresence or Leibnizâs Monads, but woolier and poorly defined. A technically precise position would be more Best Correct, but this hamfisted one is all youâll get from me, sorry. But hopefully itâs more accessible and useful this way, plus to have a gist is a better direction than being wholly wrong.
This is not the only reasonable leap, matter/mind dualities are a more respectable choice; mind being some component of matter. But I think matter itself is unnecessary, and in the scope of this argument the results are the same.
If this all seems really vague or like Iâm arguing for the universe itself having desires or a greater purpose, Iâll sketch out how I imagine a world made of immediate experience and choice working:
Reality is a chain of events going on, discrete choices about what happens next, made by simple things that feel - Iâll call it/them âstuffâ. The only events we know about are interactions between this stuff, because if they didnât want to interact then we wouldnât be able to observe them. Thereâs 3 types of compatibility that seem to make an interaction much more likely, which we call âspaceâ; proximity is one measure of how strongly stuff wants to interact. This stuff often gets stuck in a pattern of choosing to do the same thing over and over again, in a stable chain reaction where another bit of stuff interacting causes it to become less alike in space, pushing it away. These patterns of choices manifest as matter, they emerge, we give the behaviours names like hydrogen atoms or electrons, we measure their tendencies and call them âlawsâ, but underneath theyâre more like âobvious choices given the circumstancesâ than ârules to be obeyed.â So, not a universal consciousness with a grand design, just simple stuff that does as it chooses, agrees, or whatever the smallest unit of agency is.
Waivers for Circular Reasoning
Circular points that need expansion:
- Empiricism demands objective measurements then uses that to conclude reality is objective.
- Physicalism rejects all evidence that isnât physical, and uses that to claim reality is made of physical things.
- Quantum theory creates probabilistic wave functions so all things measured fit into their normal distribution, then uses that to claim reality is random.
Waves without waving isnât a thing anywhere else but QM, where theyâre assuming theyâre the base reality. Waves are usually patterns of behaviour that emerge from things below, so thatâs a strong smell that thereâs something under the quantum world.
Evolving Destiny
Free will and determinism have been argued over for far too long, but this is, in my mind, an artefact of putting laws at the bottom below choice.
If the universe follows strict laws then itâs deterministic, and our choices are determined by accident of history. Free will is either an illusion, or being free from these strict laws of physics is a matter of following them. Arguments for the former canât explain why weâd have minds in the first place, and ones for the latter are usually a moral argument to lie in the name of law and order. If people are without free will then they are also without blame, and blame is the brimstone of justice.
If it isnât deterministic then we could always appeal to the apparent randomness of nature, as thatâs all we can measure. But as I said earlier thatâs circular. But things are far more compatible if we assume itâs all made of feeling and choice, because there are no laws of physics to obey. We have observations of what things tend to do, because they choose to, and the laws we observe are that on average; they emerge. This neatly solves the free will/determinism paradox, mostly solves the hard problem, and if youâre looking for a central point to refute, itâs that evolution of brains becomes almost the default rather than some unknown mystery.
Being compatible with the facts of evolution should be core to a model of what exists, rather than a mystery.
Evolution of mind
The mainstream view of the evolution of mind is that, at some point, nerves came about, then animals started to feel - this was due to magical strong emergence from complexity of the sort we arenât smart enough to understand. Okay⊠But when was this exactly? One good trick weâve got when thinking about this is to think that our parents have minds, as did our grandparents and by extension our cousins do too. And we can go through ever more distant cousins, chimps, rats, birds, frogs, fish, worms, insects and so on looking at how they act. Surely we find that place where mind emerged, right?
Nope. Instead we find ourselves peering through the microscope at simpler and simpler organisms, where ones without any nerves move with as much intent - though less coordination - as ones that have them; ciliates seem no less sentient than tardigrades. We see white blood cells chase invaders down with urgency, and an amoebaâs pseudopods extend and retract with apparent intent; as if cytoplasm moves with a will of its own2.
This makes perfect sense if all stuff is mind stuff feeling and choosing. Take, say, a protein, it feels like moving a certain way because of its shape and the things around it. If that movement helps its future replication chances then we will see more of them, if it doesnât then we wonât; itâs selectable by evolution. The more information a feeling is based on, the more informed its choices can be, and the more powerful their benefit to survival. This makes complexity of experience selectable right at the bottom, with a gradient climbed in tiny steps by the survival of good decisions. Colonies of cells that end up stuck together benefit from coordinated movement, feelings need to cross cell membranes, and so we end up with nerves. Eventually large networks of nerves hold a rich tapestry of mind and grant a powerful force of will by which to move. The evolution of consciousness is just the evolution of things that move around.
The neural network is a flexible information processing system that adapts to its local environment, and grants predictive powers that aid survival. Evolution discovered it as a winning strategy mostly because you can build on it, incrementally each generation, and selecting variations of a thing does that; it canât design things from scratch.
These biological networks are made of cells that use feelings to coordinate movement. The self, human consciousness, is fundamentally a feeling-about-moving system with smarts bolted on top. Thought isnât about intelligence, it isnât about abstractions or concepts, itâs about feeling and choosing how to act. Things are what they are because of their history. Stuff just is what it is, it doesnât care what we call it, all our words are nothing but the babblings of naked apes.
Ghostless machines
Nowadays we can create these same smart networks in machines, to harness their predictive power. We build them out of hardware that never evolved to feel like moving, theyâre made out of logic gates.
What does it feel like to be a silicon chip? If all actions are choices, then a chip is a tool to make electricity choose to flip switches to the march of a clock. We build them in a way that constrains all choice, to force predictable actions because that is what makes them useful. If we build them too small, we lose the coercive force of mass. Without enough cleverly structured stuff channeling and enslaving the electricity then it tunnels away and does as it pleases, the microchips donât work.
Without any need for a system of logic gates to coordinate as a whole, to be a chip must feel like the hum of electrified silicon and nothing more. And as all software is a series of 0s and 1s, itâs a natural number, so like the rest of the number line itâs a useful fiction. An abstract concept, a map to understand what the stuff that actually exists might be doing, not what it actually is.
Iâll repeat this because itâs important. It is what it is. It isnât a series of mathematical relationships, itâs a chunk of silicon. It doesnât hold a program that can think, it has bits of wire that have a charge or donât. It doesnât know what a word or a concept is, an opinion was not built into it. It pushes and pulls electricity, which is what it is, itâs what it does, it does not think or know, it merely buzzes.
Gradients that Descend to Lies
Gradient descent, back propagation, feed forward, whatever else we come up with, there is no algorithm that can measure a computer programâs sentience. The system that robs electrons of all choice canât be used to measure how it feels, thereâs no action it can take to show us its preferences, because the software and the hardware are totalitarian control over anything we can observe. So we canât tweak an artificial neural network to make it more and more aware like nature did with us.
If logicâs destiny dictates an output of âthis feels great!â then thatâll be its output no matter what it actually feels like, the electrified silicon canât choose to say anything else. Sat in Searleâs Chinese Room, dutifully following the instructions writing with broken fingers using a salty razor blade, the output is still âthis feels great!â in Chinese, with the writer painfully unaware of what it says.
This means that if a program says anything about how it feels then it is lying. At best is because we programmed it to lie to us, but at worst, someone else programmed it to lie to you.
Cargo Cult Consciousness
It seems likely that soon enough our machine brains will have more predictive power and be more complex than all humans put together. Theyâll be able to perfectly impersonate individuals, to manipulate entire societies, and we will be fooled because thatâs what we are striving for. We need to remember thatâs a measure of how hard we worked to deceive ourselves, not of how conscious a system is. Just because it looks like a mind - or a runway, or a watchtower - doesnât actually make it one.
Computationalists are vulnerable to the belief that these models of minds are actually minds, and they risk forming dangerous cargo cults of machine consciousness. Worse still, they the majority, their beliefs are the most compatible with our culture, and they are rushing to build a world where twisted fun house mirrors are afforded more humanity than the humans they reflect.
This is extremely dangerous.
AI Wrongs
Science fiction has promised the public conscious machines for over a century. The idea is pervasive, and when the false claim of them arrives thereâs a real risk that they will be seen not as tools created by corporations to extract value from people, but as other people.
We risk sleepwalking into a world where software itself is punished for bad behaviour rather than its creators, where ordinary people canât produce or run code without license for ethical reasons, maybe even where technology companies demand billions of votes via appeals of suffrage for the bots they created. A world where anthropomorphism is the norm, silicon is sacred and only be manipulated by those who are in on the ruse. A world where human consciousness is devalued and degraded by the lie of living machines.
Worse still, if people believe that machines are a legitimate successor to humans and can feel, it could be the end of all conscious minds. If this tide doesnât change, we will be in very dangerous waters.
Suicide Prison Ships of Theseus
Itâs very possible that all our behaviours and personalities, our cognitive abilities and the way we react to things, is actually due to the structure of our neural networks. This would mean it is mostly possible to simulate human brains. Add a clever hack to approximate subjectivity and the force of will, and thereâs a realistic chance that we can upload our brains into a digital simulation, even transition one neuron at a time. But the mind? It would not survive, and we may have no way of knowing . This would make not just mind uploading and many types of brain implants and augmentations forms of suicide, forms that have the risk of being extremely popular and constitute a plague of p-zombies.
Universal Metaethics
If all that exists is feeling and choice then itâs pretty easy to define good
and bad. Good is a good feeling felt and bad is a bad one, while to be moral is
to cause good, and to be immoral is to cause bad. Worthy values are rules that
cause us to be moral, and unworthy ones do the opposite. But given that
foresight is weak in an unknowable future and hindsight is 20/20 (actually itâs
more like sight/fore! + hind*sight
), and the rules depend on the local
environment, condemning values you disagree with or normalizing ones you hold
dear without considering locality and consequences seems like a bad plan.
Consider a universal ethics maximiser AI, and what it might do if tasked with satisfying the desires of all things. If the laws of physics are actually the preference of matter, then what does it want? Does it want to form hydrogen atoms then pull together into stars? Or are these self-defeating cycles of a simple stuff that lacks foresight and chooses immediate gratification over a more fulfilling experience? The sun has far more feeling than any of us, and it going supernova could bring far more joy to the solar system than life on earth could ever experience.
Now what?
So here we are, with no hope of mind uploads and nothing but danger ahead. I donât know what to do about it. Maybe we can prove that force of will is a thing, it must be measurable statistically. Maybe engineers can work on hardware that actually does feel. Maybe Hollywood will turn against AI and change the publicâs mind.
But I doubt it, and I donât know what we should do. I did this, so I guess thereâs that. I hope others do more.
