1. People have been saying "this tech will make people stupid" for ages. And it's kind of true, but it's not clear that it's bad. Yes, when technology can do things we stop learning to do those things because it stops mattering. If it does still matter we would still learn.
2. I've had good conversations with ChatGPT. I didn't ask it to solve a problem, I asked it to describe algorithms, give me information about them, etc. It was a great tool. Instead of having to find a peer, catch them up, do the polite dance, schedule a call, etc, I can just say "Hey tell me about consensus algorithms. OK, tell me about some of the tradeoffs. Given this change in a data model, what changes in those tradeoffs?"
Anyway, I think this doomer view is pretty unfounded.
