I use kagi exclusively now except for shopping and images. Anytime I use Google, now I'm disgusted with how bad the results are. The bar seems really low to supplant Google search.
So what good is it finding something that’s highly relevant to my search query if it’s just garbage anyways. There are just so few sources of meaningful information, and essentially no way to reliably differentiate them from drivel.
But you're still right that there's so much garbage out there. Google had it largely under control though.
