Moore’s Law is still holding in the real world, as well as in other ways. Today’s chips have wiring that is 7 nanometer thick, but now, IBM has 2 nm thick chips. That’s smaller than the width of a single strand of DNA. 50 billion transistors in the size of your fingernail. This means performance can increase by great leaps… 45% increase in speed just on the same power, or use 1/4 of the energy.
The wiring is thinner than a strand of human DNA.
