Yes, exactly. There's some theoretical minimum amount of energy per non-reversible operation that a perfectly efficient CPU wouldn't be able to beat. > or even in developing more advanced computer chips, which may be approaching a fundamental limit dictated by Landauer’s principle. However, this last part is a bit of a stretch... Current hardware is many many orders of magnitude above this limit.
