Even Zuck realized that there is no there, there regarding the metaverse. It is just meaningless jargon spouted by desperate CEO's to snow potential investors for a year or two before they realize there is nothing there.
Sweeney usually makes more sense, but this rant is just the worst drivel I have seen him utter.
Games like Fortnight and Roblox are going to eventually hit the same snafu that Maplestory 2 did, having to shut down because they could not deal with the player created content that stole others IP. The amount of Nintendo IP designs on player created aparal got totally out of control in that game. It is clear Nintendo let them know they were not happy about this, so Maplestory 2 shut down rather than fight it. These ecosystems can not be profitable if the hosting company has to devote lots of staff to policing user content for IP theft.
