The problem I have is that if you want to engage with something like this, you need to pretend it's a human. As they say, the uncanny valley was pretty much successfully crossed. And to be honest, I don't want to pretend I'm talking to a human for a whole bunch of reasons.
The technically aspects are really impressive, but I think "pretending to be a human" in this way is a pretty scary goal. The cognitive dissonance was too strong and it was hard for me to continue a conversation very long at all. What does it even mean to have a conversation without theory of mind?
