John Carmack's arguments against building a custom XR OS at Meta

> my old internal posts... got me reported to HR by the manager of the XROS effort for supposedly making his team members feel bad

That jives with my sense that META is a mediocre company

I'm sure that kind of crap helped nudge JC out of there. He mentions (accurate and relevant) reasons why something is probably a bad idea, and the person in charge of doing it complains that JC brought up the critiques, rather than addressing the critiques themselves. What a pathetic, whiny thing to do.
