Yes, it's true that I have different expectations from a conversation with a computer program than with a real human. Like I said, I don't think of it the same as a friend.
I'm with you in that I like conversational AI. I just wish it wasn't obvious it's an AI and actually sounded like real humans. :-)
The format matters as well. Some of these things may sound just fine in audio, but it doesn't translate well to text.
Also, context matters. Sometimes I just want to have a conversation. Other times I'm trying to solve a problem. For the latter, the extra fluff is noise and my brain has to work harder to solve the problem than I feel it should.
