Search is going to be driven to zero profit, and that's going to cripple Google.
Literally everyone is empowered to build better products than Google search. And Microsoft / OpenAI will subsidize it, laughing all the way to the bottom. It'll completely poison 50% of all the money Google can make.
Google had two decades to ensure they were safe, and stuff like Killed By Google / Project Sunroof is all they've got to show for what their product culture can build.
Google is going to try really hard to reinvent themselves, but they haven't accomplished anything along that front in the last two decades. I wouldn't bet on that magic happening overnight. Their founders have been absent and their leadership has been coasting. The picture is clear as day.
Google's done. Google got checkmated hard.
