Good post, lays it down very nicely. Quick question:
Why is it that you can’t turn warm water into ice cubes and electricity, but reversible computing can use an arbitrarily small amount of energy? My guess is that computing (logic?) must be fundamentally different from work in this sense. Logic is, in a sense, ‘already there,’ whereas work requires energy.
