Programming

AI will trivialize the day to day work of programming, the really hard part of programming is being able to put together complex systems in a maintainable way. It's really more of a project structure problem than it is a programming problem. Best way to future proof yourself is to focus on the higher level architectural challenges and putting together complex infrastructure as opposed to learning things like sorting algorithms (although I don't think interviewing has caught up with that yet). LLM powered systems may eventually get to the point where it can even replace architectural tasks, but at that point almost all office jobs will be obsolete.

EDIT: Another thought, getting out of tech now is like getting out of tech right before the Internet took off. Yes AI will replace a ton of jobs and there's going to be a big reckoning, but there's a shit ton of work to get these systems in place in a reliable way. The next Gen of AI is super capable, but it's also pretty jank, and getting it to work to it's capability will require a ton of work which provides a ton of opportunity to get in on companies that will become big when they do it well.
