I agree with @[email protected] about it having the capacity to make older adults feel less lonely. At the same time, however, I think it seems very dystopian. If someone was feeling sad or depressed we wouldn't say "oh, just chat with this AI until you feel better". So why is it okay to suggest this for older lonely people who are especially vulnerable?
Hell, given what ChatGPT has told people already it might do more harm than good. It's akin to the whole of humanity saying "Yeah, we know you're lonely but getting an actual person to talk to you is too hard. Chat with this bot."
