There’s not much time left to develop reversible machines, because progress in conventional semiconductor technology could grind to a halt soon. And if it does, the industry could stagnate, making forward progress that much more difficult. So the time is indeed ripe now to pursue this technology, as it will probably take at least a decade for reversible computers to become practical. I believe the opposite: companies should wait until performance improvements in mainstream processors have really ground to a halt before investing substantial resources in reversible computing. Otherwise it will be a financial sinkhole like many prior attempts at exotic computing hardware that couldn't make a sustainable profit. The only path suggested in the article that could be pursued right now involves superconducting devices, requiring cryogenic cooling that will never work for phones, tablets, or laptops. A company would be trying to catch up with a tremendous head start enjoyed by CMOS plus conceding that the new hardware, even fully realized, will never address markets as broad as CMOS.
