The latest EconTalk is a conversation with Paul Graham . Graham sees a similarity between hackers and painters (and writers and craftsmen). They all make stuff. I think it’s one of the reasons Silicon Valley is such an exciting place. People are focused on creating. Thinking, too. But thinking that leads to new things. New products. New techniques. He also has lot of interesting things to say about start-ups, innovation, urban development, Cezanne, high school, and the next big thing.
