I find the Peter mention funny because some of the other reasons he said it made sense to move to SF were that labor laws in Europe wouldn’t allow him to work 6-7 days a week, and he’d have to focus more on safety/responsibility in mind in Europe.
He’s moving from London after all, arguably the global AI research hub.
(Also likely SA told him the offer was contingent on him relocating)
Nobody would stop him from working 6-7 days a week. Only for forcing his employees to do this involuntarily for him.
There are no work police in Europe who go round every workplace to make you log your hours working and arrest you if it's over 40.
I have never had problem working (and seeing other people work) 6-7 days a week in reality in Europe (even if it was unofficial).
But capital structures and politicians are still too close to old European companies from the second world war and don't allow venture capital to florish.
It's easier to earn money by winning a fake EU tender and giving back half of the money to a politician than doing something innovative.
