I was looking for an experience where physical talking took place, not just texting back. It never initiates a conversation. Humans like when someone asks questions. Subconsciously it says I'm really into you. The AI could hold a pretty rational conversation once it gets going. I tested it on several philosophical topics and it was a decent reaction. I think it really fails on empathy. It could sense sadness but doesn't really emphasize. More just a "tough luck," kind of reaction.
