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

> they also got me reported to HR by the manager of the XROS effort for supposedly making his team members feel bad

This is madness. The safe space culture has really gone too far.

I'll offer a different interpretation:

If a professional can't give critical feedback in a professional setting without being rude or belittling others, then they need to improve their communication skills.

From what you know of Carmack, does "can't give critical feedback in a professional setting without being rude or belittling others" sound like him to you? It does not to me, though granted maybe he's different in his non public persona than what you can see in presentations and talks.
