I live in a country where the internet is very restricted. I do not use a VPN on my laptop, but I do occasionally on my phone. Western AI is blocked.
What I have noticed, anecdotally, is that people embracing AI appear to be the folk that never really mastered using the web. I don't mean that in a condescending way, because using the web is really a matter of time, patience, and determination.
Wiki for example, great for an overview, but the real power of it is in the footnotes, where the core data is referenced. And it can take time to go through it, data handle it digest it, then present it.
Many folk don't have the time, so they appear to have skipped the web search stage, and gone straight to AI.
Problem is of course, AI is not always accurate. And if the user is not familiar with the subject, then what AI is pumping out might look fantastic, but it is often just rubbish.
This was in addition to something I saw recently, where someone claimed very few people where I live have a search engine on their phone, they just use apps. I done a quick straw poll, and it was true. Everyone I asked never used the default search on their phone. They used apps only, and now AI ( the local one). It was a very small straw poll.
I totally share your concerns re wiki and the like. It really is worrying.
