I remember talking to someone who had worked on reversible computing about 13 or 14 years ago, and he had said that (i) it does work (presumably that it is indeed more energetically efficient), but (ii) the state of computing was such that it may be a couple decades before it can make a real impact (). Then he added, "someone else can have that fun." Around that time he switched to working on other things. () Unfortunately I can no longer recall exactly what he meant.
