> We have no idea, what causes the sensation of subjective experience.

Agreed.

> Assuming that sentience is no more complex than our current level of understanding is arrogant.

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.
