Quite surprised to see more comments are negative about the technology, but myself I beleive it is really possible but not going to happen in very short time like in 18 months, it will take atleast 5 years to roll out the beta and the development will go on for years. Why Mark started too early is to establish he wants to take the first seat so more profits than back seats but as far as the investors concern towards is understandable but they took the bet so have to accept the outcome as well.
But he is burning billions without a product in sight! Metaverse as we can see it in some promo videos is still far away, and 18 months or 5 years is a pretty long time... he will probably burn even more billions until that point! I don't think that people are negative, it's just reality. For metaverse you will need VR, and how many people have and actively use it?! And do we really need it? How many people are really interested in the metaverse? Do we really need some other reality like the one we can see in some movies?
I guess the metaverse can be interesting, but let's keep it within some limits! We also need to stay humans who need some real touch!
