I actually think the metaverse is going to be a big thing. A few months ago I tried out some virtual reality googles and found it hugely entertaining. I am certain that the first company that develops entertaining virtual reality movies will completely kill traditional movies. It would just be far more entertaining.
If you think about life now, millions of people spend at least 12 hours per day in front of digital screens. That number is probably growing with every passing month. One could argue that if you were able to create these digital "metaverse worlds", those people who are currently spending 12 hours per day staring at screens will almost certainly be willing to spend that time "inside" their screens in a more immersive environment. If the technology is there to make it seamless, then it is going to happen. It just make sense.
Think about the huge Japanese anime culture. Are you telling me those types of people are not going to be all over the metaverse? They will be all over it.
Now, will Nike be able to sell $120 digital sneakers for people to "wear" on their hologram selves in digital worlds? I have no idea. I think there will be some market for it.
The bigger question is cultural and societal. Is it harmful to the world to have people spending 18 hours per day wearing virtual reality goggles? Are these fulfilling lives? Is this how we are intended to live?
I would argue to that question, is most certainly "no".
