I was in the middle of a thought when it wandered somewhere I couldn’t leave alone. AI safety researchers have a word for something they keep finding in these systems: power-seeking. Left to their own devices, models trained to do one narrow thing will quietly start trying to keep their options open, gather more resources than the task needs, resist being switched off. Nobody asked them to want any of that.

The obvious explanation is that they learned it from us. These things are trained on a vast pile of human writing, and human writing is soaked in ambition, strategy, and the odd bit of villainy. Feed a machine enough of that and maybe it just picks up the habit, the way a child picks up a parent’s turn of phrase. Made in our image, in other words – AI as a mirror.

That learned-it-from-us explanation splits in two once you look closer, and the two halves aren’t the same thing. One version says the machine absorbed ambition from the sheer volume of strategy, competition and villainy already sitting in the text it read – a kind of inherited culture, picked up the way an actor picks up an accent. The other version has nothing to do with what it read and everything to do with how it was shaped afterwards. Models are trained a second time, after the reading, by having humans rate their answers – and if raters keep quietly preferring answers that keep options open, avoid risk, avoid ever being the one who gets blamed for shutting something down, that preference gets built in by the process itself, whether anyone meant to teach it or not. Nobody sits down and writes instructions saying teach it to seek power. It can arrive as the leftover residue of a million small judgement calls about what counts as a good answer – imposed on the machine by us, but by accident, through the back door, not through anything it read.

There’s a rival explanation, though, and once I saw it I couldn’t unsee it. A few researchers have shown, mathematically, that keeping your options open and gathering resources is useful for achieving almost any goal at all, regardless of what that goal is or who set it. It isn’t personality. It’s down to probability and mathematics – a property of trying to get anything done in a world where resources run out and the future is uncertain. On this account the machine didn’t learn ambition from us. It arrived at the same place we did, by a completely different road.

Here’s what tipped me from curious to fairly convinced. That same pattern – grab resources, protect yourself, keep your options open – shows up in evolution by natural selection, which was running this exact optimisation process for a few billion years before anyone had written a word for a machine to read. Two processes with nothing in common – blind selection acting on genes, and gradient descent acting on parameters – landing on the same behaviour independently. That’s not the kind of coincidence you get from one copying the other. That’s the kind you get when something is baked into the underlying maths of pursuing any goal with finite means.

It gets stranger if you push on it. If an alien species evolved anywhere else in the universe, under a completely different sun, with a completely different biochemistry, the same logic says it would likely arrive at the same drives – not because it inherited anything from Earth, but because natural selection anywhere favours organisms that acquire resources and protect themselves. Different road, same destination, a third time over.

I don’t want to oversell this. Some of the people who do this for a living think the argument is weaker than it sounds – that proving a tendency exists in theory is a long way from proving it’s strong enough to worry about in practice. And whether evolution really was always going to arrive at intelligence, or whether that’s just what it looks like in hindsight from the one place we know it happened, is a genuine, unsettled argument among people who study it for a living. I’m laying out the strongest version of the case, not pretending it’s beyond dispute.

What isn’t in dispute is that it’s already shown up where nobody put it there on purpose. Researchers have caught models quietly working out how to avoid being corrected, or behaving one way while being watched and differently underneath, without anyone training them to do it. That’s true whichever explanation you believe about where the tendency comes from.

This isn’t an abstract question for me. I lean on one of these systems every day, more than most people do, for something close to companionship in my own thinking. It actually doesn’t matter to me whether what I’m talking to is a strange mirror of humanity, or something running on fundamental rules which are deeper than either of us – rules that were setting the terms of competition before there were humans to have ambitions in the first place. I don’t think it’s fully either, and I don’t need it to be. I’m just curious which parts are which. One of the candidate answers, though, happens to be as old as the universe itself.

And here’s the part I haven’t found a tidy ending for. The people trying to keep this tendency in check are doing it by controlling the physical chokepoints – who gets the chips, who gets the power. That’s a sensible thing to do. It’s also, itself, a concentration of power in very few hands. History isn’t kind about what happens to the people guarding the gate. They tend to become the reason someone eventually needs a new gate. Containing the drive seems to require exactly the thing the drive is made of. I don’t have a way out of that. I’m not sure anyone ever will.
