Who will build new search engines for new personal AI agents?

IMO - Personalized search engines are awful and have ruined the ability to find and discover new things. I liked it when you used to watch YouTube and then end up watching weird stuff you would never think of just by the pure chance of randomness. Now YouTube's algorithm, all it does is give you more of the same stuff you watched before, no variety anymore.

"hey go book me a place for drinks tonight in Peckham, it needs to have food and not be insanely busy"

The information needed to answer this request often just doesn't exist on the web. Often the true answer is obscured by lies. Personal agents don't have the ability to perform due diligence in a web of lies.
