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.
Mark wouldn't allow all gis efforts to be put into nothing so I believe that Meta still has a huge potential to boom in the future. It's just that we all have too high expectations of it but we should still give it a chance and time to develop. It couldn't reach our expectations for now because the market is still in a bullish situation it couldn't go through its full potential. Let's wait and see until its fully developed and built.
