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.

How is this your problem? The streamer is taking on all the risks.

And we were talking about children.

A little late to the thread, but wanted to add my 2 cents anyway. It's not exposure itself to sexual that is the issue, it is encouragement (implicit or explicit) that the children emulate or partake in the same behaviors. For every ancient civilization that mated in front of their kids, how many also mated with their kids? Don't be too quick to dismiss the long term mental effects on exposure and normalization of sexuality to the sexually immature.

I think you're right with the ancestral environment, however I don't know whether the types of contents you can find on the internet are in the same ballpark and whether or not they have a negative impact on a child's development.

24/7 available video streams available on any internet connected device is not comparable to real life authentic chance encounters.

People don’t want to dig too much into it as either it will show it’s a problem, or show that advertising is ineffective.
