Search WAS good when it was a simple search. Sites were indexed by the search engine and if you searched for the words you wanted to find, the results would be exactly that. In that context, it worked perfectly.

But the problem was that most people used search engines in a different way. They weren't searching for specific content, but searching for answers to questions. And for that, search engines would only show results that had that same question and then you'd need to hope that the question had been answered.

Over time, search engines kept shifting into trying to better support the questions and answers format, making the basic content search worse as a result. Where we are now, neither or them works too well. Google is now better at understanding what people are trying to search, but worse at finding it.

AI is just expanding this with yet another layer: it might make Google better at understanding what you search and maybe even might be better at finding it than the engine is now, but it'll add the ability to misinterpret the results too.

Honestly I'd be pretty happy if I had a simple indexed search again.
