As soon as I learned about this miracle of chip making I thought, what is the key missing element? ... I'd been working on software so I decided that maybe that was what was necessary to bring all this power to life. I talked about that with a friend, Paul Allen, and we kept saying, "What can we do? Can we start our own software company?" It seemed impossible at the time because software was not done by independent companies. The companies that built the computers - IBM and DEC - they did all the software. And when we called them up and said, "We would like to do an operating system," they said, "who are you?" to which we said, "we're high-school students."
