If this were a common sentiment or rooted in reality I would imagine their stock would not be at an all time high...
I gave up on Chrome a decade ago, going back to Firefox. I don't use Google for search anymore, I do use Gmail but I also got Protonmail so could easily migrate the Gmail traffic there.
A lot of non-techies I know have complained for some time how Google search sucks, and while a lot use Chrome it seems to be mainly inertia.
Not saying Google is dying, but it seems vulnerable for disruption.
I wouldn't be surprised if most of it was already tried in some form.
