I also agree that specialized forums have well-managed aspects. But conversely, getting into a specialized forum usually required a ticket of admission—something like having to attend a certain conference socially.
So the problem is this point. Very high-level forums required an admission ticket, or basically a certain level of qualification, and were hard to get into; you had to get in through an existing member, and if you were physically far from that member, it was hard.
Usually, the forums someone like me could get into were often ones at a somewhat lower level. These days things move to Discord, but it's hard to go into Discord's closed ecosystem and study there.
Actually, as you said, forum activity and human interaction are important. Because in the end, humans have to learn about the world through humans.
The world isn't simply a place to obtain information—things like the patience to endure unpleasant situations and people, the understanding to listen to others' opinions without distorting them, and the courage to admit to others what you don't know are not things that can be cultivated through AI, I think.
The various values that have limits when learned through AI can be learned by mixing with people. In that sense, people have to learn about the world among people.
Because AI basically gives you wrong information to please you and reinforces information only within the scope of what you already know. I think friction with people is necessary to find keywords you genuinely don't know.
My words got sidetracked in the middle. I agree with your comment that AI isn't the only thing that changed the internet this way, and I also agree with your point that forum activity and the like are necessary. It's just that where we put the emphasis and weight is what makes our thinking differ. Thank you for the long comment, and have a good day
