I assume that you are assuming assumptions. When you assume, you make an
"ass" of "u" and "me", don't you know? Or I assume so, in any case.

What's a computer engineer? Is that a dude that designs hardware? Or is it a
fancy name for cable monkey?

This is where the metaphor of Consciousness is Computer Process falls down.
Of course, a process can be swapped out and in (and is routinely, under a
multiprocessing OS), switching from a running "thing" to information and
back again. The external observer cares not at all about these interruptions
to the processes' "continuous identity"; it makes no functional difference.

Also, the process itself cares not a whit, because it has no means to; it is
not conscious, after all, so how could the concept of caring mean anything?

However, a conscious being is another kettle of fish. Being swapped in and
out may be a problem for a conscious being; interesting ramifications for
hardware & OS design for upload sim environments.

I am contending that consciousness is not information; it's a thing that
exists in some way. A process in a computer is not information; its a stream
of activity undertaken by a physical machine. It is very closely described
by information; a dump of the contents of the memory that it is using, the
registers, OS tables of IO states, etc. However, it is not that description,
and it is not the file or process table entry or whatever, that is stored
while it is swapped out. It is not even the contents of it's memory
addresses and the registers, and all that guff, while it is running; it is
the actual things being done while it is running, as a result of those
contents. Atoms flowing around, gates doing gatey stuff, hardrives whizzing,
stuff happening. Not information.

Undoubtedly this is possible, undoubtedly this will work, especially from
the point of view of the engineers & admins building and running such
systems (ie: from the outside). What will the subjective experience be for
those so encoded, however?
