I honestly don't see these Metaverses adding much value.
Most of the value is going to come from decentralized projects that build on metaverses. Not developed by big corporations, but rather by grassroots organisations and groups that have much more motivation than profits.
This seems to be the clear recipe for success in the cryptospace at least.
if you have an idea for such an application you can get a development grant from the deso team and make it on the deso blockchain
