From WSJopinion: It is the 50th anniversary of the launch of the Intel 4004 microprocessor, writes Andy Kessler. I’m convinced that most wealth created since 1971 is a direct result of the 4004. All of tech. All of finance. All of retail.
The world changed on Nov. 15, 1971, and hardly anyone noticed. It is the 50th anniversary of the launch of the Intel 4004 microprocessor, a computer carved onto silicon, an element as plentiful on earth as sand on a beach. Microprocessors unchained computers from air-conditioned rooms and freed computing power to go wherever it is needed most. Life has improved exponentially since.
Back then, IBM mainframes were kept in sealed rooms and were so expensive companies used argon gas instead of water to put out computer-room fires. Workers were told to evacuate on short notice, before the gas would suffocate them. Feeding decks of punch cards into a reader and typing simple commands into clunky Teletype machines were the only ways to interact with the IBM computers. Digital Equipment Corp. sold PDP-8 minicomputers to labs and offices that weighed 250 pounds.
