Hours worked isn't the problem. It's super easy to work a ton when the motivation is right.

Google becoming organizationally deadlocked is the problem.

It bears repeating: Google _basically invented_ the transformer architecture and were out-executed. Doesn't matter whether people were working 40 hrs remotely or 100 hrs per week on-site; this is an organizational failure.

Anyway, it sucks to see Sergey sell out like this.
