Google thinks there’s more money in feeding you slop forever. With ads. And a subscription.
I don't think that's the long term goal. First, they slowly phase out the actual information sources, by making it so you aren't linked to other websites. Now you've got a dependent group who rely in AI as a source of truth, and now they can modify "the truth" whenever you want because it's the only source left. They could re-write human history and only people with books would know the difference.
