That's the crux of the matter. Conscious experience cannot exist in determinstic worlds. In finite sized worlds, such as calculators, any deterministic algorithm is equivalent to a giant lookup table: (input, memory) -> (output, memory), all four entities have a finite fixed size. For infinitely expanding deyerministic worlds it's more complicated, but it's obvious that such worlds have to expand at the expense of some outer realm, as you cannot create more GBs of memory out of thin air. This problem with determinism has a theological angle (I've warned you). The so called "fallen angel" believed that consciousness can exist in deterministic worlds, and he had an impressive design of such a place. That world was created, but his vision never materialised: his mind was vast enough to imagine such a world, but not enough to see its subtle deficiency.
