Extropic founder @beffjezos reveals how their chips achieve 140X the energy efficiency of GPUs by computing with the jitter of electrons: "This is not even a digital computer. We can even encode continuous numbers with a single pbit. If you average it, you can encode a number in the average, and the more samples from the average you get, the higher the effective precision." "Our pbits use about 10,000 times less transistors than if you were to emulate them digitally. It's because we actually…
