For online friendship to really work, we need to solve the problem of pig-butchering scammers (scammers who "make friends with you" and eventually get you to give them money somehow, e.g. by depositing money in a "crypto trading platform", sending money for a "health crisis", etc.)
This problem will only get worse with conversational AI agents/deepfakes/etc. For every human seeking genuine friendship there might be 100 AI agent scammers.
