I am agnostic about whether it will ever explain why those beings actually have qualia, and don't merely act like it.

I wouldn't call myself as "agnostic" on that- I would claim that it's an unquestion if it doesn't cash out as differing predictions in a materialistic interpretation. (This is sometimes what people mean by agnostic, but typically agnostic describes the "above my pay grade" response, not the "beneath my notice" response.)
