> I'm sure the engineers at Google worked 4 days a week, 2 hours a day

Why are you sure of that? Anecdotally everyone I know in and around Google Deepmind works incredibly hard.

No disrespect to the Google Deepmind team, but I meant it as a meme. I do not believe most Google employees work 2 hours a day.

The Google Deepminds are incredibly smart - I just find it important to point out that the xAI guys spent a year assured they would beat Google because they slept in tents that they made in the office.

There’s a longstanding meme that Google is full of rest-and-vesters. Maybe it’s true in some departments, but I also have anecdotes that in GDM and other AI-related stuff, people are acutely aware of the existential threat of losing to OpenAI and have the appropriate amount of hustle.
