I've been predicting this for a while.

The issue is coming up with ways to impact the AI's stats based on your interaction. How do you determine whether xyz text makes an ai more or less fond of you? THIS is why lots of people think we are still missing a very key feature in turning these ai into truly sentient beings. They need an internal value structure, and we need to find out how to establish what impacts that structure and how it impacts it.

It's so complicated, that I find it difficult to really word my thoughts on the subject.
