First we replace judges, doctors, police, generals, state officials, politicians, etc etc, and only then the programmer, the true foundation of our society!
(It shouldn't need stating that replacing any of these professionals with AI systems as they exist today is a terrible idea. Yes, even the politicians)
LLMs are good at processing natural language. I think only a few human tasks are suitable to be fully replaced with AI. Things like translation might be a good candidate, with some proofreading.
I could see LLMs easily doing the job of newspaper sports reporting, for instance, taking the stats and a few main facts from last night's game and turning it into a narrative article. It just wouldn't be good at long-form pieces that go into depth about motivations and strategy.
