I worry that as the tools for creating virtual worlds improve they will continue to be used for creating opportunities for child exploitation (Roblox) or general profit from the sale of user privacy to the businesses and demagogues with the most money to spend (whatever Meta's doing).

Not a proponent of virtual. The virtual is a mistaken path to reach the brain's topology, it's inherently 2-D. So the path is probably a hybrid between post-symbol and topological integration, ie 2-D screens.
