"Why Cars Are Better Than Horses" Clip from Interview with Bill Gates, 2009

Obsessively dedicated to computing and software since his student days, Bill Gates became galvanized by the advent of an early personal computer, the Altair, which appeared in 1975. His passion for seeing what the computer could do was so great, in fact, that he took a leave of absence from Harvard and moved to Albuquerque, New Mexico, home of MITS, the Altair's parent company, to write code for it. Capitalizing on this initial success, Gates and his team went on to write the programs in BASIC for the IBM PC that proved instrumental in launching the personal computing revolution.
