> Social media has given me a rather dim view of the quality of people's thinking, long before AI. Outsourcing it could well be an improvement.
Cogito, ergo sum
The corollary is: absence of thinking equals non-existence. I don't see how that can be an improvement. Improvement can happen only when it's applied to the quality of people's thinking.
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.)
