Supposedly the internet was most used, in the beginning, by jen watching porn. if they want to make VR popular, they need to make porn interactive somehow. Nodes that can be attached to a man’s sensitive areas and maybe to his hands. That would take a long time to put on - if there were tiny wires in a super-thin body suit that were a bit like nylon stockings, then that might help. That’s a great way to finance it, I think. The technology isn’t there, yet. But, I think robotics technology could be combined with VR somewhat - in the suit, that is.
