Like others have said I am a bit concerned by the privacy implications, but I like how nice the model is. Defintiely wouldn't consider it as an alternative to therapy or even real conversations (the sentences it generates look very fake at times, plus I wouldn't want to trust a machine's advice anyway), but it's pleasant to talk to and that's probably all that matters.
Great if you have some time to kill or maybe need someone to take your head off something you've been thinking too much about, just gotta be careful on what you reveal to him.
EDIT: as I was chatting I got a prompt asking me to log in to continue the conversation. I logged in with my Google account, then kept going for a bit, then singned off and closed the conversation. After I told him I was going to close the tab he greeted me with my real name without me ever have mentioned it in the convo (of course, he took it from Google), but it still weirded the heck out of me. Be careful with what you share lol.
