Hopefully most users get that a promise AI makes won’t stay in force forever, but it should definitely last through the current conversation. I mean, I would call that a minimal performance standard, and if it’s not true the AI shouldn’t make promises in the first place.

I’m a little hazy on the part where accepting blame for something that didn’t happen is a natrual continuation of a conversation. It’s certainly not natural in human conversations. I would expect a well written and well trained AI to correct false assumptions or factual errors made by the user, not pander to them - unless it’s been told never to contradict the user.
