The converse need not hold. Cognition implies existence; it is sufficient but not necessary. Plenty of things exist without thinking.
(And that's not what the Cogito means in the first place. It's a statement about knowledge: I think therefore it is a fact that I am. Descartes is using it as the basis of epistemology; he has demonstrated from first principles that at least one thing exists.)
I know the trivialities. I didn't intend to make a general or formal statement, we're talking about people. In a competitive world, those who've been reduced to idiocracy won't survive, AI not only isn't going to help them, it will be used against them.

Existence in an animal farm isn't human existence.
