Good for him. No one has done as much damage to AR/VR as FB did to it with the Metaverse. Way to make something cool fundamentally unlikable.

It was obvious that there would be no space for Yann LeCun after Alexandr Wang came in. He was probably just waiting for the best time to leave.

I cannot judge his research output at Meta but he failed pretty bad at the LLM race. Since so many other organizations succeeded at creating open source models of far higher quality at much lower cost, it would be instructive to understand what exactly went wrong there.
