The first two iteration of this were AMP and Instant Answers, the third one is AI Overview. AI Overview should not be seen in isolation, but as a part of the pattern. If it weren't for it, Google would double down on some other method of reaching the same goal.
This one will end up the same way the other two did: there's gonna be a vocal minority that's gonna consider it unfair and a web killer, the vast majority of users won't have an opinion, Google will not care, "the web" will play along, those early adopters are temporarily gonna have an advantage in this "new age" and some will die in the process, but the vast majority is gonna continue on as if nothing happened.
It's also not gonna be the final iteration of this process because shiny new things sound better to investors than marginal improvements, so X years from now AI Overview is gonna be seen as something "old-fashioned", Google Search will pivot once again, and the rest of the web will follow to keep Google happy.
