Moore’s Law, a prediction from 1965 that the number of transistors crammed into circuit would double every two years, has an expiry date. The problem is scale. The latest chips from Intel have silicon transistors with features as small as 14 nanometers. Theoretically you can have a feature as small as a single atom, but before you reach that point – at about 7 nanometers, things get weird. You leave the conventional world of classical physics and open a portal into the trippy reality of quantum physics. That’s bad news because by 2020, in order to keep up with Moore’s Law, the industry will need to be down to five nanometers.
