Eighty per cent of microchips are in household use already - and that percentage will actually go up. There is a whole industry in Japan trying to invent applications for very very cheap microchips.

The main point here is that the same data can be held or read by computers as by other sorts of electrical devices. In theory, a microwave could read digital data as well as a Cray supercomputer. The only difference is the power to process that data, and microchips have become so small and cheap that you will be able to build a super Cray into a microwave if you really want to. The start of this was the telephone system.
