That is, did the designers copy human algorithms for converting sensory inputs into thoughts? If so, then the right kind of experiences would seem to be guaranteed
You seem to be rather sanguine about the equivalence of thoughts and experiences.
(And are we talking about equivlanet experiences or identical experiences? Does a tomato have to be coded as red?)
Or did they find new ways to compute similar coarse-grained input/output functions? Then, assuming the creatures have some reflexive awareness of internal processes, they're conscious of something, but we have no idea what that may be like.
It's uncontroversial that the same coarse input-output mappings can be realised by different algorithms..but if you are saying that consc. supervenes on the algorithm, not the function, then the real possibility of zombies follows, in contradiction to the GAZP.
(Actually, the GAZP is rather terrible because irt means you won't; even consider the possibility of a WBE not being fully conscious, rather than refuting it on its own ground).
I'm not equating thoughts and experiences. I'm relying on the fact that our thoughts about experiences are caused by those experiences, so the algorithms-of-experiences are required to get the right algorithms-of-thoughts.
I'm not too concerned about contradicting or being consistent with GAZP, because its conclusion seems fuzzy. On some ways of clarifying GAZP I'd probably object and on others I wouldn't.
I found this article on the Brain Preservation Foundation's blog that covers a lot of common theories of consciousness and shows how they kinna miss the point when it comes to determining if certain folks should or should not upload our brains if given the opportunity.
