Finally I find this argument. Agreed, and I'm baffled that people think that AI is what's going to "solve loneliness." Loneliness has already been solved by YouTube/Twitch. The brain is easily tricked into thinking that it is "being social" when it is subject to the effects of the parasocial relationships that are formed by these platforms. People's afternoons are rapidly becoming consumed by hours of YouTube where they come out of it with a brain telling them: "boy, that's enough social interaction for today!" Introversion has become an epidemic as a result.
It's not just streamers - fictional characters are also increasingly engineered to be this way. Besides the loot box aspect, many East Asian gacha games are built with parasocial relationships with the characters in mind, for one.
