In 1971, the first integrated circuit was built using a mixture of photo lithographic and chemical techniques. This has been an enabling technology for virtually everything that has already been mentioned.

In 1971 a transistor radio would have perhaps 10 semiconductor junctions and ran off a circuit board about 10cm x 10cm. An iphone has 2 billion semiconductor junctions, which implies a circuit board about 4.5km square. (it wouldn't work, but it is an interesting calculation).
