For the same search quality they have now, and in a world where Kagi exists for $10, no.

I read a lot of wikipedia. Probably ~10 articles per day. Some people watch Netflix, I read wikipedia. If I search for <famous person name> or <historical event> with no additional context, I want the wikipedia article 99% of the time. Sometimes google is fine and it's the top link, but sometimes it's not even on the first page. This regression is pretty frustrating for my (admittedly niche) use-case.

If Kagi didn't exist and my choice was only between 0$ ad-tier google and $5 no-ads google, I would pay the $5. I pay for YouTube premium to get rid of ads there.
