TL;DR: Yes it's possible, but it doesn't actually matter if it happens or not. An AI creating websites is definitely possible, but will it actually replace people? I don't see that happening (at least not at a large scale). It's much more likely to be a tool that developers use rather than a tool that replaces developers. Or possibly something similar to Squarespace. It might be able to manage content on its own and build webpages, but what happens when there's a bug? What happens when you want to innovate and create something new? An AI would have trouble accomplishing that, so web developers would still play a role. Now the more important question in my mind isn't whether or not they will replace jobs, but rather does it matter if they do? And my answer to that is no. There's two scenarios. A scenario where AI completely eradicates all developer jobs, in which case AI has probably eradicated a majority of today's current jobs and we would adapt as a society. Either by instituting some changes like Universal Basic Income or by developing new job markets (probably geared more towards the arts or things we can't yet imagine). The second scenario is that AI is introduced more as a tool or a simple solution to web/app development. In that case, there will still be a need for devs to do the more complex stuff. There will also be other development fields to move into, like Machine Learning Engineer for example.
