This has already been the case for a while with "Zero-click searches". It's when you look up a trivial piece of info that can be said in one line. Google will show that sentence on the search results. You don't have to click through to the full page.
The best part is that product wasn't even that accurate, and has no qualms about showing you straight up bullshit or a lie stolen out of context from whoever did the actual research.
Google is ahead of the curve in how ready they are for LLMs!
And if you opt out google will eventually just push you down.
