Using the same opening words as you:

Believe me, this guy was far from the first to show up in a metaverse. Remember Second Life? Well Susan Vega done a live concert back in 2006 already: @michaelmaddof/metaverse-concerts-the-future-of-music And before her other bands did.

Believe me: Though quite some peeps will pay for and attend a virtual concert, I'll not attend as long as metaverses don't give the feeling of the real deal to real concerts and festivals. That may still take a few decades to get there (real life visual, smell, taste, feel sensing are required) :)

But I do agree, a lot of money will be made through virtual worlds, these days popularised under the term metaverse. However, metaverses are completely hyped at the moment, like Second Life was back in the days. After the hype, we'll see a major DIP in metaverse usage. Gamers will stick around and some others, but the reality will be most of use will get all we need and want through the 'traditional' channels.
