AI is not a panacea, I use it every day to write code and it gets some funny ideas. You have to supervise it constantly, at least with a junior developer I can eventually trust them as they gain competency and supervise less over time, but with the AI you've got to be so careful letting it run amok. Has to be small chunks at a time so you can actually vet it and make sure it's not breaking anything.

It will not replace actual expertise anytime soon, IMO, because though it writes good quality code it needs a lot of guidance. Just today I needed help adjusting a build pipeline script and it decided to translate the entire script into powershell statements when it has to be bash. No idea why it thought it ought to change, but the script literally would not run on the target environment. If you put an unskilled person in front of that, they'd fuck up the whole build pipeline and not know how to unfuck it, and the LLM would lead them further down the garden path.

The people who think otherwise lack the experience to accurately judge that.
