Haha. I think that most of today's gamblers will remain to play in our usual online and land-based casinos because we are already used to it. Of course we want a new experience but I don't think many of us will be able to spend time in the metaverse on a daily basis. In my opinion it is similar to the way they once released TVs with 3D that almost no one watches at home now.
Great example! I even managed to forget about this phenomenon, although quite recently it seemed so cool and progressive. There were also Google glasses and several other similar projects.
In general, to be honest, now the Metaverses at this level of technical development cannot offer something really necessary and the projects that I see now (or their discussions) remind me of the "solution in search of a problem" scheme.
In my opinion, today the metaverse is just a way to attract attention to the project. The same can be seen in many projects launching NFT, which have no real application and have nothing to do with the economics of the project. Naturally such projects fade quickly. Many projects working on the metaverse expect the same prospects and only teams creating something unique will succeed.
