So, one meta-layer of discussion up: do we think the recent surge of Kagi discussion on HN is indicative of a real wave? Or is “picking a different search engine” gonna be something only 1% of users ever do again? I honestly think that even if Kagi does remain pretty niche ( serve that niche (so far… mostly HN-user-types, I would bet). But it seems hard to make money at that scale and with a non-advertising business…
I don't think that seems hard at all, really. Companies do it all the time. What it makes hard is becoming a multibillion dollar behemoth, but that isn't (and shouldn't be) everyone's goal.
