Last time I checked, the metaverse was all about people collaborating in the making of a shared world, and we already have this. Examples include minecraft and vrchat, both of which are very popular metaverses. I don't see how not having bot content generation is a barrier?

Then, let's say people are allowed to participate in a metaverse in which they have the ability to generate content with prompts. Does this mean they're only able to build things the model allows or supports? That seems very limiting for a metaverse.
