  Nevertheless, this cannot be taken to imply that analysing the thermodynamics of computation is an altogether pointless task. The question of whether or not one can deduce thermodynamic consequences of physically implementing logical operations, from the structure of the logical operation itself, may be a well-founded question (although it clearly cannot be wholly divorced from what fundamental physics says about the construction of such devices). Furthermore, were it to be shown that Landauer's principle was not correct, and that information could be reset at arbitrarily low cost, it would seem that either untamed demons must be possible or some further source of heat generation must be discovered in the operation of Szilard's engine.
