To add some clarification, I do not think spreading Alice's logic gates
across a field and allowing cosmic rays to cause each gate to perform the
same computations that they would had they existed in her functioning brain
would be conscious. I think this because in isolation the logic gates are
not computing anything complex, only AND, OR, NAND operations, etc. This is
why I believe rocks are not conscious, the collisions of their molecules may
be performing simple computations, but they are never aggregated into
complex patterns to compute over a large set of information.
