Up to now, the Gemini results they display are often worse and less accurate than the same question asked in Gemini. I'm guessing SEO has so thoroughly cooked Google's search results that they are actually holding back Gemini as a brand.

It looks like the new experience works backwards - it's more or less a Gemini prompt that they then stuff a "search experience" into.

Obviously the search feed and ads are so integral to Google's business model that they probably can't confidently just step away from it.
