You may be imagining a future where AI can do all jobs, but please be clear that this is your imagination. That future does not exist today and is not guaranteed to exist tomorrow. Before it can exist, a much simpler future where AI can replace any job has to exist, and that future doesn’t exist yet either.
assuming the premise of the thread, that some hypothetical AI replaces all the developers, I was questioning why such a hypothetical AI would be able to do the work of developers, but not do the supposed "new jobs" jotjotzzz believes would arise.
basically, if AI ever becomes autonomous and general enough to fully replace developers, it will be autonomous and general enough to handle any new jobs that pop up too.
