There is no way to convey this without being a little bit of a jerk, but I think your take demonstrates being out of touch, in the "no wireless, less space than a nomad, lame, also Dropbox is just some tooling around rsync" sense that HN tends to get sometimes. This is enough of a phenomenon that other mainstream artists are starting to get into it, which means there are enough people getting joy out of it for it to have a market of its own.
I think you ignore the metaverse (the concept, not Facebook's janky implementation) at your own peril. The next generation is growing up with virtual concerts, and in many cases virtual artists.

And that's not counting the upcoming stuff. Trying to write off something this successful as a pandemic driven fad kinda speaks to that whole being out of touch thing I was talking about.

There's no demand to watch computer animated concerts through heavy glasses in Fortnite coming from people who don't already spend a bunch of time playing Fortnite. This is an add-on to Fortnite, not anything that anybody really wants to do for its own sake.
What's the point of watching a computer animated "concert" in VR anyway? Who would get any joy out of that?
