> This isn't to say that semiconductors will stop improving The funny thing is they might stop being semiconductors actually. > Digital logic integrated circuits (ICs) implemented with complementary metal-oxide-semiconductor (CMOS) transistors have a fundamental lower limit in energy efficiency because transistors are imperfect electronic switches, having non-zero OFF-state current (IOFF) and finite sub-threshold slope. In contrast, electro-mechanical switches (relays) can achieve zero IOFF and perfectly abrupt switching characteristics. https://www2.eecs.berkeley.edu/Pubs/TechRpts/2017/EECS-2017-21.html https://www2.eecs.berkeley.edu/Pubs/TechRpts/2017/EECS-2017-... And the work on the optical technologies to use instead of transistors are massive recently.
