I'd say bollocks to that. Entropy is clearly information in
disguise. That changes in it can also be related to the amount of heat
processed at a given temperature is also something that comes out of
considering rearrangements of kinetic molecular motion, and ultimately
gives rise to the well known Landauer limit on computing.
