Google search requires a lot of resources to crawl, keep indices up to date, and provide user level significance (i.e. different results to different users).

Gemini/Claude are as good, for the most part. And users don't care that much either - most use the standard free ChatGPT, which likely is worse than many competitors' paid models.
