The reason I pay for Kagi is that I specifically don't want this to occur.
Every person I have seen (outside the tiny tech bubble) google something has just read the AI overview without skipping a beat.
[EDIT] Incidentally, are there any sites that do actual web search any more, better than Yandex? I'd rather avoid a Russian site if I can, but there are whole topics where it's impossible to find anything useful on heavily "massaged" allegedly-Web-search-but-not-really sites like Google and DDG (Bing), but I can find what I want on page 1 or 2 of a Yandex search. Is Kagi as good as that, or is their index simply ignoring a whole bunch of the Web like so many others? I don't mind paying.
Yes, people want the answer directly. Google wants you to stay on their site to read some mishmash. I think the ideal would be to immediately go to the source’s site.
A search is just learning what you don't know and AI does a better job than search has ever done for me - and I'm in tech.
This leads directly to another big change.
People used to submit their sites to search engines and now they might actively block search engines. So a search engine author might have to spend a lot of effort in adversarial games.
Also a lot of site owners are reluctant to link out. So much so that 'nofollow' had been reduced to a hint rather than a directive.
