Ok, I see what you mean, and I agree. I would guess that it might be more
convenient to move information around instead of energy, but you're right
that the same thermodynamic effect can be achieved either way.
Earlier you mentioned that most normal forms of matter has maximum entropy
that is proportional to mass, but a black hole has entropy that is
proportional to the square of its mass. Of course this is what allows
black holes to have such low temperatures and be used as heat sinks. But
what I'm wondering is if there is some non-black-hole arrangement of
matter that has maximum entropy that is proportional to the square of its
mass (and has a reasonable volume). If such a thing exists then we can
perhaps use it as a memory store and never have to erase anything.
