MrSeb writes: "IBM has demonstrated a 9nm carbon nanotube transistor (CNT) — the smallest CNT ever made, and significantly smaller than any commercial silicon transistor. At 9nm, IBM’s transistor is also smaller than the physical limit of silicon transistors, which is around 11nm. IBM's CNT operates at an ultra low voltage (0.5V), thus consuming less power than its silicon counterparts. The difficulty now, of course, is mass production — but considering other foundries seem to be sticking to silicon for as long as physically possible, if IBM can somehow squeeze out some CNT chips, this might be the edge it needs to challenge Intel for semiconductor supremacy."

I have yet to see any problem, however complicated, which, when
you looked at it in the right way, did not become still more complicated.
