This is Grady Booch up on the Big Giant TV, telling us all about the history and future of computing. Booch has been Rational's Chief Scientist since it was founded in 1981 and has written a series of widely-read books on software engineering. He invented object-oriented design and developed the Unified Modelling Language along with Ivar Jacobson and James Rumbaugh. OK, that doesn't mean anything to you, does it? But he's a Big Cheese in the Rational world.
