Exponentials exist in their environment. Didn't Covid stop because we ran out of people to infect. Of course it can't keep going exponential, because there aren't exponential people to infect.

What is this limit on AI? It is technology, energy, something. All these things can be over-come, to keep the exponential going.

And of course, systems also break at the exponential. Maybe AI is stopped by the world economy collapsing. AI advancement would be stopped, but that is cold comfort to the humans.
