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

It matters who you communicate concerns to. Something as fundamental as "I think that your team shouldn't even exist" should go to the team leads and their managers exclusively at first. Writing that to the entire affected team is counterproductive in any organization because it unnecessarily raises anxiety and reduces team productivity and focus. Comments like this from influential people can have big mental and physical health impacts on people.
