It would completely force all companies to address the problem and quickly. The discourse about online activities of children in these videogames would immediately hit breakfast tv and be in front of the eyes of moms everywhere, globally. When they hear and see what is going on (because the media would sensationalise the shit out of it) the steam behind regulating it and getting the online portion rated would pick up pace rapidly.

You bet they'd be fucking eager to regulate themselves when that train got rolling. If the tech exists to handle this now then we should push for it. The excuse they had before was ultimately that it was impossible to really moderate voice interactions between people, AI will make that no longer true and it opens the door to really pushing the issue.

I think leftists should consider joining in on that (but not wearing your red flag). Taking away the reactionary nature of the videogame online space would hurt the Gamer™ to alt-right pipeline.
