Or more likely Google couldn't give a rat's arse whether those AI summaries are good or not (except to the degree that people don't flee it), and what it cares is that they keep users with Google itself, instead of clicking of to other sources.

After all it's the same search engine team that didn't care about its search results - it's main draw - activey going shit for over a decade.

Google AI Overview a lot of times write wrong about obvious things so... lol

They probably use old Flash Lite model, something super small, and just summarize the search...
