I have a strong memory of watching a Jacques Cousteau documentary on sharks and learning that Sharks could become mortally wounded but not realize it because of how their nervous system was structured. As a kid I thought that was funny, as an engineer watching companies in the Bay Area die it was more sobering.
If you have read the article, I think Gomes was right and saw search as a product, whereas Raghavan saw it as a tool for shoveling ads. A good friend of mine who worked there until 2020 wouldn't tell me why they left, but acknowledged that it was this that finally "ruined" Google.
Their cash cow is dying, I know from running a search engine what sort of revenue you can get from being "just one of the search engine choices" versus the 800lb gorilla. Advertisers are disillusioned, and structurally their company requires growth to support the stock price which supports their salary offerings. There is a nice supportable business for about 5,000 - 8,000 people there, but getting there from where they are?
My best guess at the moment is that when they die, "for reals" as they say, their other bets will either be spun off or folded, their search team will get bought by Apple with enough infrastructure to run it, Amazon or someone else buys a bunch of data centers, and one of the media companies buys the youtube assets.
