I don't find any real usability for this Metaverse: actually I think it will only make people and society dumber and closer to the Idiocracy movie. Spending time online wearing some stupid glasses it's a no no for me. Also the NFTs are a waste of time and money, I wouldn't buy useless digital shoes and buildings. I love BTC and have diamond hands but these 2 things I'm not a fan of and I know I will never be. Society needs to become wiser not dumber. Living in a digital realm sucks, I'm a human being not a stupid machine. Rant over.
You're definitely not the only one that has thing opinion. The Metaverse aka controlling a virtual avatar in a 3d world seems to be a perpetual idea that gets re-imagined every ten years and someone tries to give it a big push. Granted each iteration gets steadily better (anyone remember second life?) and what Zuckerburg claims to want to do this time might be a wild leap forward, but ultimately it's just a virtual world - a step away from reality. NFT's seem like a gigantic waste of money, the sellers are rolling in money and the buyers seem to be easily influenced people who must be the type to waste money buying a lot of virtual junk, 99% of which will be worthless in a couple years.
While I agree I think this time around there is going to be a big push for this idea to become a reality, Facebook is losing members on their platform for a variety of reasons so Zuckerberg is trying to find another way to keep them or to even increase the number of people using his platform and he thinks the metaverse is the right way to do it.
This means that he will invest a fortune in order to make this a reality, and if enough people buy into the idea then it is likely we will see the metaverse gaining traction and then becoming incredibly popular.
