We're really handicapped by a lack of definition, here.

Let's try this: what would it take, no matter how outlandish or unlikely, for you to be completely convinced that a particular chat bot demonstrates full sentience?

I think for me, it would never be able to fully demonstrate sentience to my satisfaction, because even people cannot. I have to take it on faith, philosophically speaking, that you are sentient, for example.

So, for me, if a chat bot feels and behaves like it's sentient, it is sentient for all real, practical intents and purposes, irrespective of its internal processes. Whether it "really" feels, like I do, is as irrelevant as whether you yourself "really" feel like I do. Without a good reason to believe you are not sentient, I must behave as if you are. Likewise, if a chat bot claims sentience and seems to hold a conversation and react the way I expect a sentient creature would, it would be unethical for me to ignore that because I didn't feel its code was sufficiently complicated, particularly if I cannot say for certain why anything is sentient.

I don’t think that’s an interesting question at all and misses the point completely.

We have no idea, what causes the sensation of subjective experience. Assuming that sentience is no more complex than our current level of understanding is arrogant.

Furthermore, it’s just plain useless; without a fundamental theory of sentience with both predictive and explanatory power, our understanding can’t grow.

Agreed.

Agreed. I'm assuming nothing. Given that we don't know what causes the sensation of experience (nor even that it has any real meaning or use), in my opinion, the assumption that it cannot possibly involve "Markov chains" is arrogant.

> Furthermore, it’s just plain useless; without a fundamental theory of sentience with both predictive and explanatory power, our understanding can’t grow.

Well, sure. It could be that sentience doesn't have any scientific relevance at all. Questions regarding it may belong to a different magisteria altogether.
