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.
Of course, it does not destroy Google's income ... and it destroys the promise Google made long ago, which is to never keep users on Google platforms.
Oh and to add insult to injury, want to bet Opal will force app developers into what you probably never even imaged would happen on the web? Pay-per-view. Not for a video. For a website/app.
They're here, they don't care how they get from point A to point B, the tech used to achieve that result is completely irrelevant to them. AI? Great. Not AI such as the Instant Answers era? Also great. Average Joe does not spend his time thinking about the economics of the web.
But you shouldn't confuse them finding "AI" useful now with them being attached to it long term. It's a hip new tool now, but the novelty will fade and Google will have to re-invent themselves all over again. If anything, they kinda screwed themselves over by calling this "AI". AI is supposed to be something within reach, but always some years away. By wasting that term for the current era, it's gonna suck so hard to think of a new marketing term that's gonna be seen as an improvement in comparison to the term "AI".
Neithet do any teams at Google, including the search teams. Google is an ad company with 80% of its revenue coming from ads. They couldn't give two shits about the health of the web.

As for Google, what I wrote was literally spelled out in their own emails uncovered in court proceedings.
