摘要：In a short but interesting book, computer pioneer Ted Nelson takes
a very broad look at the origins and evolution of many of the basic
ideas that underpin today’s computer industry. The emphasis is on
concepts and technologies rather than the success of individuals, the
companies they founded, and the shape of the computer industry.
This approach differentiates the book from other accounts, such
as Robert X. Cringley’s Accidental Empires and Martin Campbell-
Kelly’s From Airline Reservations to Sonic the Hedgehog.
