Actually Google is already doing this. Results are personalized and contextual. It can't really know what I feel like eating this evening because I don't, but it can guess.
I applaud the author for trying, but I don't see an alternative to PageRank being proposed. How exactly is Kagi proposing to rank results?
And no, I don't want an AI generated summary when I search for the best tutorial to do X. I want a list of tutorials. The question is how to rank that list, and I've yet to see anyone do a better job than Google.
Google is far more than PageRank. Its an AI ranking model that has the largest training dataset (queries and clicks).
Ads may suck, but simply charging for the same service isn't really innovative. Would I pay for a version of Google without ads? Probably not. But that's just me - I actually like to know who is advertising for particular searches. A company with an ad budget to rank at the top of ads is probably more trustworthy than an anonymous website.
