My background is in cognitive science and psycholinguistics. I spent more than ten years talking to first year psychology undergraduates about whether AIs could be conscious; also did some research on (extremely tiny) AIs in modelling language behaviours.
There is a great deal of good thinking on Chiang's topic by professional philosophers, and there's much to be said for reading them. I won't rehearse their ideas here. Chiang's arguments might be correct; but I suspect they probably aren't, and his error may well stem from characterising human thought as something in its own class, which is probably a cognitive bias that humans have. He might also - I'm speculating - be arriving at his conclusion based on his feelings, which the final paragraph suggests (the comment about the models being based on morally dubious actions).
Speculation aside, we are not, I believe, in a position to make points like he does with any certainty.
