“To be conscious is an illness, a real thoroughgoing illness.” — Fyodor Dostoevsky, Notes from Underground
Prologue#
Here’s something that sounds so simple but gets weird fast: being smart and being self-aware is not the same thing at all. Ants can solve complex problems and build structures that give medieval castles a run for their money. The inconspicuous slime mould can navigate mazes and sprawl across entire forests. Neither of them lies awake at night wondering what the point of it all is, tossing from one side to the other on a bed , or whatever thing they sleep on. We humans do. Constantly. It seems we are the only species that carries the weight of knowing we exist. The worthless pile of atoms knows it is actually worthless.
In this essay-ish blog, I want to explore whether that awareness is what makes us special , or if it is simply a very expensive mistake.
The Book That Started This#
I was nudged down this rabbit hole by a fairly brilliant sci-fi novel called Blindsight by Peter Watts. Its central theme revolves around consciousness , what it is, what it costs, and whether it is actually necessary for intelligence. Give it a read if you are into this kind of thing.
Summary for my fellow lazy compatriots , and spoiler alert if you are planning to read it. The story kicks off when mankind encounters visitors from space. Being the self-appointed flag-bearers of peace (I know), we decide to communicate. A crew is assembled for the mission , including a vampire, yes they exist in this universe, but that’s a whole other story , and they board a spaceship called Theseus. They make contact in the Oort Cloud, near a region called Big Ben, with an alien vessel dubbed Rorschach. Communication happens, sort of, until the ship’s linguist figures out that Rorschach is not actually talking , it is mimicking. Like a very sophisticated echo. When the crew boards Rorschach, they encounter the Scramblers: nine-legged alien creatures with more raw brain power than the entire human population, but which dedicate that brainpower almost entirely to sensory processing and locomotion. They are closer to white blood cells than people , components of a system, not individuals within one. They have no consciousness. They share a collective hive mind, forgoing individuality entirely for operational efficiency. They are, by every measurable standard, terrifyingly competent. War breaks out. Humans lose. One survivor escapes in a pod to relay information back to Earth.
According to Wikipedia, Blindsight is the neurological ability to respond to visual stimuli without consciously perceiving them. It is an apt name for the enemy humanity encounters , a form of intelligence that surpasses us while being entirely unaware of itself
The Chinese Room Next Door#
Before we get into the aliens, there is a thought experiment worth stopping at. The American philosopher John Searle proposed what he called the Chinese Room.
Imagine you are locked in a room. Messages written in Chinese come in through a slot. You have an enormous rulebook,a Chinese-to-English dictionary and your job is to follow its instructions and send back the correct responses. To anyone outside the room, you appear to understand Chinese perfectly. But you don’t understand a single word. You are just following rules. Searle’s point was that symbol manipulation is not the same as understanding. Processing is not comprehension. Intelligence is not awareness.
Blindsight takes this thought experiment and gives it teeth. The Scramblers are a Chinese Room the size of a spaceship. They process, respond, adapt, and survive with extraordinary efficiency and understand nothing. They simply do not need to.
The Case Against Consciousness#
Let’s be honest about what consciousness actually costs before we start defending it.
The human brain uses roughly 20% of the body’s energy despite being only 2% of its mass. A significant chunk of that energy is burned by the default mode network, the part of the brain active when you are doing nothing in particular. Daydreaming. Ruminating. Replaying an embarrassing conversation from three years ago at 2am for no useful reason. This is not an optimised system. This is an engine that idles loudly and burns fuel while parked.
A hive mind like the Scramblers does not have this problem. Every joule goes somewhere productive like locomotion, sensory processing, threat response. No committee meetings. No identity crises. No therapy.
Consider also what consciousness demands beyond the purely metabolic. Other animals do not need their lives to mean something. We do. And to meet that need, every human civilisation in history has independently invented mythology, philosophy, and religion;elaborate systems for managing the terror of being a conscious creature in an indifferent universe. We built entire cultural architectures just to cope with the fact that we know we are going to die. The Scramblers don’t have a religion. They don’t need one.
Consciousness also introduces operational lag. Doubt. Dissent. Hesitation. A hive mind acts with perfect coordination and zero deliberation. It decides (if you can even call it that) and executes. Consciousness, by contrast, creates space between stimulus and response, and we fill that space with anxiety, second-guessing, and debate. In a cold universe competing for resources, that is a liability.
By every clean efficiency metric, the Scrambler model wins. Consciousness looks less like an evolutionary advantage and more like a very strange, very expensive detour.
The Case For The Detour#
But here is where the argument flips and why the detour might be the whole point.
Fire was discovered very early in human history. Somewhere around a million years ago, some ancestor of ours noticed that controlled heat could transform things;meat became safer, warmth became portable, darkness became manageable. That discovery alone cascaded into agriculture, metallurgy, industry, and eventually the server farms running the AI that helped write this sentence.
Was that a hive mind achievement? Maybe the coordination could have happened collectively. But the specific leaps , the moments where the framework itself was shattered and rebuilt , those required something the Scramblers structurally cannot do.
A hive mind is the perfect optimiser within a given framework. It can refine, accelerate, and execute. What it cannot do is step outside the framework and ask whether the framework itself is wrong. That move , the metacognitive rupture , requires a self that is separate from the collective. It requires the loneliness of individual consciousness. History moves through these ruptures. And almost every one of them was, at the time of its occurrence, an act of irrational stubbornness against a consensus that was confidently, efficiently wrong.
Galileo was not working with the consensus of his time, he was destroying it. The prevailing model placed Earth at the centre of the universe, backed by centuries of scholarship and institutional authority. A perfectly calibrated hive mind, optimising within that framework, would have continued to produce increasingly sophisticated geocentric astronomy. Galileo’s consciousness , his individual, obstinate insistence that the mathematics mattered more than the hierarchy , is precisely what made him dangerous, and eventually right.
Ignaz Semmelweis, a Hungarian doctor in the 1840s, noticed that doctors were killing patients by going directly from performing autopsies to delivering babies without washing their hands. Germ theory did not yet exist, so he could not explain why handwashing worked , only that the data was undeniable. The medical establishment mocked him. He was eventually committed to an asylum and died there. He was right. A hive mind calibrated to mid-19th century medical consensus would have been confident, coordinated, and lethally wrong.
Closer to home: B.R. Ambedkar looked at a social order thousands of years old, validated by scripture, tradition, and overwhelming consensus, and said , this is wrong, and I will prove it with my life if I have to. That is not the output of a system optimising for local efficiency. That is one conscious individual deciding that the entire framework needs to be thrown out. The cost to him personally was immense. The consequence for hundreds of millions of people was transformative.
This is the pattern. The hive mind cannot produce a Galileo, a Semmelweis, or an Ambedkar. It cannot produce anyone who turns to the collective and says we are mistaken. Because there is no “anyone” in a hive mind , only the collective, which by definition agrees with itself.
The Randomness That Generates Novelty#
There is a deeper principle at work here that is worth naming directly.
Evolution itself works because of random mutation — not optimised mutation. Pure optimisation would have locked in the first viable organism and stayed there forever. The errors, the accidents, the strange detours are the source of all novelty. Diversity emerges from imperfection.
Human consciousness operates similarly. The ruminating, the dreaming, the irrational obsessions — these are not simply waste products of a poorly designed system. They are the substrate from which new frameworks emerge. Einstein developed special relativity partly through a daydream — imagining himself riding alongside a beam of light. That is not efficient cognition. That is consciousness doing something no Scrambler ever could: generating a productive error, a useful hallucination, a model of reality that did not yet exist.
The very features that make consciousness look like a bug — the lag, the doubt, the individual dissent — are also the features that allow it to escape local optima. A hive mind is extraordinarily good at climbing the hill it’s already on. Consciousness can look at the hill and ask: what if there is a taller one somewhere else?
The Key#
So here is where we land.
Consciousness is not humanity’s greatest strength by the metrics that matter in the short run. In raw efficiency, energy use, operational coordination — the Scrambler model wins. The burden is real. The cost is real. The suffering is real and unshared by anything else on this planet.
But a key is not valuable because it is the strongest object in the room. It is valuable because of one specific structural property, it fits a specific lock. Consciousness is humanity’s key to a particular kind of lock: the ability to reject the current consensus from the inside, to step outside the framework and redesign it, to make the kind of leap that no optimised system can make because optimised systems, by definition, do not break from what works. A hive mind is a battering ram. Extraordinarily powerful. Perfectly coordinated. It will break down any door you aim it at. But certain doors cannot be broken down. They have to be unlocked. And for that, you need the key.
Humans, in a cosmically brief period of time, went from rubbing sticks together to landing on the moon to sequencing the genome to arguing about artificial intelligence over the internet. No other lineage on Earth has done anything remotely like this. And almost none of it happened because we were efficient. It happened because individuals, often at great personal cost, looked at what everyone agreed was true and said: no.
The Scramblers were formidable. Likely more so than us by almost any measurable standard. But they never had a Galileo. They never had a Semmelweis. They never had a moment where one of them turned to the entire species and said — we are wrong, and I can prove it. That moment — lonely, costly, irrational, and deeply human — might be the only thing that makes the burden worth carrying.
We pay a steep price for knowing we exist.
It turns out, that is exactly what the universe charges for the ability to change it.
We are the cosmos made conscious and life is the means by which the universe understands itself.” — Brian Cox
