Steve Wozniak, or "Woz" as he is commonly called, is best known for co-founding Apple along with high school friend Steve Jobs. But Wozniak didn't set out to establish one of the world's most influential computer companies. His goal early in life was to be an engineer and a lifelong employee of Hewlett Packard -- and to have enough spare time to tinker with electronic gadgets. Knowledge@Wharton spoke with Wozniak on a wide range of topics, including: his relationship with Steve Jobs, artificial intelligence, companies he admires in addition to Apple, the state of education in the U.S. and his upcoming appearances on Kathy Griffin's television show, "My Life on the D List."
