The difference is that hot tub twitch isn't an actual interaction between two people, its a dopamine feedback loop that warps an un-jaded mind into thinking it's reality.
Is that also true of VR games, games in general, multiplayer games, concerts,TV, videos, watching a streamer play games, movies, social media etc. etc.?
Yes, I think so, just to a lesser degree. People playing VR half life Alyx don't actually think they are part of a human insurrection fighting alien overlords but an alarmingly large number of people watching these hottub streams think they have some legitimately romantic connection to the streamer, or a chance of it. Young men can be remarkably stupid in this way.
