> Every post about Google for years has been people saying it's terrible and dead.

They are terrible, but that doesn't mean anybody else is good or better. And being better at search isn't enough anyway [1]. Also, when you give Google less of your searches, personalization drops off and it gets even worse, but most people give all their searches to google so they see the benefit of personalization if they compare.

[1] When Yahoo did user research on search, one of their findings was that if you asked users which results were better, there was a strong and consistent preference towards results that were shown as Google results, regardless of the actual results. It's been forever since I saw those reports, so I don't remember the numbers, and the numbers are likely different today anyway, but that's a huge barrier to adoption that you have to manage.
