They didn’t exactly stop innovating: ChatGPT itself is using tremendous amounts of innovation that was done and published by Google. What they stopped is beating their competition to launching compelling products based on the innovation they do.
IMO this whole narrative reflects a type of human bias and the reality that we didn't evolve to reason about trillion dollar complex business.
I love chatGPT but it clearly has a ton of issues. To declare Google dead that is point is completely absurd.
I can't think of a single transformative technology that actually has a first mover advantage. The first, second and third mover seem to make all the mistakes and setup the forth mover to learn from those mistakes for free and create a monopoly.
Counting out a company that owns Deepmind is just not rational.
Nearly all of the authors left Google years ago. If the company doesn’t keep the people innovating it’s not like they’re some magic middle manager who can make it happen without them.
