For my programmer friend who wanted to know about MacWrite and MacPaint, I suggested watching James Burke's great Connections series, which I've written
about previously. Every "invention" is more of a synthesis of ideas that were floating around. This is the brilliance that makes change possible. If we had our priorities straight we wouldn't honor the lone inventor (an idea that I don't think even exists) rather we'd celebrate the synthesizer, the Rolling Stones, who loved the music of American blues musicians and figured out how to make it relevant to everyone, but never forgot their roots. Just one of a billion examples.
