From his tweets.. >I see no reason to expect that Meta could build a better CPU/GPU than Qualcomm (at much lower volumes!), and there isn't as much opportunity for full custom special units in VR as people think. This leads people to propose lots of MR features, which are of unproven value. https://twitter.com/ID_AA_Carmack/status/1603936133632905216?s=20&t=BtYUFO8CBLEkBqGwUqC9tQ https://twitter.com/ID_AA_Carmack/status/1603936133632905216... I wonder if John is just not a believer in MR (mixed reality) that this is what actually led to him leaving. I could see him advocating strongly for pure VR, as its his bread-and-butter and where he probably believes is the most innovation. MR presents challenges and ideas he might not be well suited for.
