"I’ve never worked for musk or his managers — but I’d assume that if folks are high output he would not care how often they were in the office" I have and believe me it's kind of random and dependent on the mood. The problem is that even if you are a 100x engineer the guy in the bad mood today may not know or care who you are.
I can't understand why anyone would willingly take a job at one of his companies (but especially Xitter) at this point just knowing what's publicly known... but it's also not difficult to find someone who has worked for him and can tell you what that experience was like.
I wouldn't be surprised if the % of people working on X on an H1B rose since Elon took over.
