I think you and the parent comment are both wrong. The right analogy is something like a new species, which consumes resources and makes more of itself. The species is "AI", or "AI-empowered organization with a handful of humans on top", whichever way you like to think of it. It doesn't have to be winner-take-all, there can be many such things running around. But the point is humans can't compete with such things and will lose resources to them. Something like Factorio, with the "players" building automated production chains everywhere, and the planet's native critters (us) not very important as workers or consumers, simply pushed out whenever we interfere.
The technical term is ‘mirror life’.
A data centre the size of Gormenghast, with the remains of humanity clinging like limpets to the outer walls, trying to stay warm.
