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.
I guess people don't fully understand what a metaverse is, it seems like they are just looking at projects labeled as metaverse that are active in the crypto and they don't know that the metaverse has been in development for a long time and is heavily invested by tech companies. I also think the metaverse will be an important trend in the future as this technology becomes more and more popular and VR devices become cheaper, people will realize how useful it really is.
In my opion and what I read about the topic in the forum - - I think META is really trying to make something big here and they are definitely trying to preparing for something big. We might see them failed but I think they are serious about this Metaverse and they will not lose that much if this is not worth it.
