A lot of it comes down to the Quest processors as they are just not very powerful. It had to be backwards comparable with the 835 Snapdragon processor form the Quest 1 and that is a 2016 processor. Makes senses it was so basic as they wanted to have many avatars on screen at once so things had the get cut…like legs. Ahahahaha.
I am not defending Meta, but just stating the facts and one of those facts is Zuck has said this is a long game and that it will be at least a decade before the Metaverse becomes something half compelling. I agree with that assessment. It is just not there today, but it will be.
