Organelles might not be Turing oracles, but they can compute folding problems in constant time or less. And I was trying to point out that you can't implement Vista and an x86 emulator on any other hardware for less than you can Implement Vista directly on x86 hardware.

EDIT: Considering that the evolutionary search took longer to find mitochondria from the beginning of life than it took to find intelligence from mitochondria, I think that mitochondria are harder to make from primordial soup than intelligence is to make from phytoplankton.
