In a general sense, yes. I think S/H systems can simulate understanding as in weak AI but that they cannot have conscious understanding as in strong AI.
And conscious understanding affects behavior including the behavior of those neurons associated with understanding, making weak AI itself a formidable challenge.

If you bring to me a simulation of water that "actually includes wetness" then I will ask why you call it a simulation of water. Sure look like real water to me.
And no I don't think s/h systems can have first-person consciousness of that real quality of wetness, of what you might call the quale of wetness.

In the broadest sense I mean the having of conscious experience of any kind, but we concern ourselves here mainly with the kinds of mental contents most closely associated with intelligence, e.g., the experience of understanding words and numbers.

I agree that evolution selected conscious experience, but perhaps only because nature found it more economical than the alternative.
