AI will kill the volunteers run websites and blogs faster then it will kill corporate ones. It will kill free information first. It will basically finish the process google search engine started when it started to require seo to find stuff.

People will have less or no motivation to create them, because well, why would they? It will be just a food for AI of some corporation.

And more importantly, people won't be finding and joining communities that produce the websites like stack overflow.

It was nice while it lasted, but likely it will be something that existed only for one generation.
