> A devastating criticism to the pattern view is that it hypothesizes a
perfect copy. If we assume consciousness must emerge from a physical brain
(qualifying an upload computer as a brain), there is no such thing as an
identical copy of anything in the universe without invoking very extreme
quantum environments that may be out of the reach of any upload machine.
Copying a computer program requires separate hard-drive space or a separate
floppy disk. The copied program behaves identically when it interacts with
a computer, but it has a separate existence.
2 possible replies:
identity is a matter of degree, not absolute. a reasonably good upload may
make you a different person to a small extent, but so might a change of
or identity is a matter of preserving certain features which are robust to
small perturbations, eg, attractors in perceptual systems.
