What is Moore's law? Are robots taking over the world?

In 1965  Gordon Moore, co-founder of Intel,  observed that the number of transistors per square inch on integrated circuits had doubled every year since the integrated circuit was invented. Moore predicted that this trend would continue for the foreseeable future source
Computers are getting faster and (relatively) cheaper with each passing year. The phones we carry in our pockets are far more powerful than the ones that sent the Apollo astronauts to the Moon.

We are now approaching half a century of the integrated circuit. Fascinating discussion about the accelerating pace of change in BBC In Business Podcast - Race Against the Machine (March 30).
