Even just today: reality is Google is 4th place to OpenAI, Anthropic, and Meta in AI and its not really close.
Each individual step is arguable, but the cracks are there. And leadership is too MBA-y/trend-following to do anything about it.

Then once Mark started firing, all that went far away, promos were held, and there's ceremonial cullings weekly.
