You think programmers are indispensable? "Learn to code"?
I think you, likely as not, have a rude awakening ahead of you. GPT can enshittify code, too. Unwind libraries into oceans of repeated Copilot-descendant code all over the place. It'll just take longer.
Just imagine how much tech debt can be generated by an overuse of GPTs... One concerning scenario is if software needed for e.g. garbage collection or food warehousing has some critical bug, but the AIs can't fix it, and the human employees (and even consultants) have a very hard time figuring out what's going on too..
GPT doesn't do anything on its own, it needs a prompt.
That prompt is basically code, written by a programmer, although it resembles natural language so we're closer to usable literate programming than we've ever been.
Programmers didn't disappear with new (higher-level) programming languages, if anything there have been more of them; how is this different?
