For me the whole Meta thing is pretty high up there for failure potential.
I grew up reading William Gibson and Neal Stephenson, I even made a cyber-glove as my high school graduation project, so the whole metaverse idea sort of appeals to me.
But I doubt the hardware is going to be at a level that's transparent enough to the user anytime soon to want to use it for any extended period of time.
I think Apple has potential to succeed with some limited version of AR whenever they release their rumored device, but I doubt a full-on cyberpunk-type metaverse could succeed unless it's an open protocol, and even then it's a solution in search for a problem.
I'm sure though, if Zuckerberg keeps pouring resources into it in some pretension to becoming the father of the metaverse, that progress will be made, I just doubt his company will benefit much from it.
I was thinking though, if something like that did become real at some point, as an open protocol, if a person wanted to carve out their own visual representation of a piece of 'cyberspace', you'd probably want to base it on something like Etherium to allocate the required computation resources.
