just like you don't need webmasters, if you remember that term. IF you are just writing CRUD apps, then yeah - you're screwed.
If you're a junior, or want to get into the field? same, you're totally screwed.
LLMs are great at soft tasks, or producing code that has been written thousand of times - boilerplate, CRUD stuff, straightforward scripts - but the usual problems aren't limited by typing speed, nor amount of boilerplate but by thinking and evaluating solutions and tradeoffs from business perspective.
Also I'll be brutally honest - by the time the LLMs catch up to my generation's capabilities, we'll be already retired, and that's where the real crisis will start.
No juniors, no capable people, most seniors and principal engineers are retired - and quite probably LLMs won't be able to fully replace them.
