Forums like this may die, but chat boards like Matrix, Discord, Slack will come out on top I believe.
Anything with Voice chat. I think we’re still a little ways off from them being able to simulate a talking conversation in real time. The API delay with these AIs is what gives them away.
Once you have talked with someone you know they are real. As well if you really wanted to confirm people in your community are real you could do voice chat vetting.
Convincing someone for a scam is one thing, convincing someone you’re having an actually thought out conversation with inflections and emotions and logic all making sense is another.
If we get to that point the system as we know it will be over anyways.
