We don't need no Artificial Idiots,
we have enough real ones…
The whole topic of AI has a myriad of issues, but as far as websites go, here's a few pertinent things:
Firstly, much of what is touted as being AI is not intelligence (understanding), but just machine‑processing of data.
AI-generated content can be completely bogus, misleading and actually detrimental. And it's often confidently presented to you as if it were gospel. Idiots spouting nonsense is actually harmful to the sum of human knowledge. It makes even more people dumber.
It could supply you with data that someone else has the rights to but you're not aware of. This could land you in copyright hell, or seriously damage projects when someone is doing research (e.g. land you in patent hell).
Over time, search engines started out by finding for you what was probably the best results for your query. Then the results became the sites that paid most for advertising on the search engine, which often skewed the results away from what might have been the best sites for you to look at. Then it started paying more heed to forum websites and ignoring individual ones (*). Now AI presents its idea of a summary of a website (which may not be a very smart summary), and people use that summary instead of going to the site. The AI bot has scraped the web to serve its own purposes, and is no-longer contributing value to the sites it indexed. It's self-serving and completely exploitative. You may have created a website which advertises your services, and provides useful information about such services, and related info, to the public as a drawcard. Now the ability to do that has been greatly diminished. The AI bot took your information without permission or payment, and wants you to pay them to advertise you. It's the ultimate capitalist bastard.
