>> this show is one of my favorites, too, every year. thanks for having me. >> you studied da vinci now. before that ben franklin, albert einstein, steve jobs. some people regard henry kissinger as highly innovative. if somebody says what makes somebody innovative at that historical level? >> especially with steve jobs, ben franklin and einstein you look around and they love to cross disciplines. they love the humanities and the sciences. leonardo da vinci is sort of the ultimate. somebody who wasn't just smart but had a playful curiosity about everything there was to know. just like steve jobs loved design and loved, you know, calligraphy but also loved electronics, i think innovation comes from crossing discipline.
