People don't want to interact with the human-generated content, why would AI-generated content change their minds? I have yet to meet anyone who uses the metaverse, and it's not for lack of funding on Meta's part.
Until I locked my headset down my kid got onto the metaverse a few times without me realizing, and playing a bunch of random “experiences”.
VR Chat was less locked down and felt more self patrolled and honest. (On the other hand I wandered a common “watch a movie” vrchat video room instance where Nazi propaganda played and the people in the room were bro-asting about being racist anti-semites.)
