The past 70 years have seen the way we live and work transformed by two tiny inventions. The electronic transistor and the microchip are what make all modern electronics possible, and since their development in the 1940s they’ve been getting smaller.
Today, one chip can contain as many as 5bn transistors. If cars had followed the same development pathway, we would now be able to drive them at 500 000km/h and they would cost just R60 each.
