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.

If I was on that team I'd welcome the opportunity to tell John Carmac why he was wrong or if I agreed start looking for another project to work on.

When I was on nuclear submarines we'd call what you are advocating "keep us in the dark and feed us bullshit."

This assumes that you would be sincerely listened to, which you wouldn't in a case like this. Higher ups in large organizations don't have the bandwidth to listen to everybody.

Your sub's officers also need to constantly be aware of what to communicate to whom and in which language. Your superiors certainly kept you in the dark about a ton of concerns that were on their plate because simply mentioning them to subordinates would have been too distracting.

You say your piece and if not heard, do an internal transfer. This whole don't tell people the truth about technical matters to not hurt their feelings or disrupt some people's paychecks is not serious business.
