In advance of the release of his new memoir, Source Code: My Beginnings, Bill Gates sat down with GeekWire for a wide-ranging conversion on topics including his extraordinary upbringing in Seattle, the key people and influences in his life, the remarkable circumstances and luck that led to his work in software, and his outlook on the world today.

We're presenting this interview in two parts, this one focusing on Gates' new book and his life, and where the world is headed from here. On an upcoming episode, as part of our Microsoft @ 50 series, we'll hear his thoughts on the evolution of the company that he and Paul Allen started five decades ago, the opportunities in artificial intelligence, and what's next for Microsoft and the industry.
