Freeman Dyson reminds us that hand-eye coordination means more than skill.

What’s unique to the audience of the videogame medium is that there’s a medium within the medium: the hand. Games revolutionize how we interact, and tools revolutionize the world. Or this is how Freeman Dyson, treasured (and lambasted) 88-year-old physicist and mathematician at Princeton (who’s been called “heir to Einstein,” but is weirdly skeptical of global warming) sees it in his 1999 book, The Sun, The Genome, and The Internet: Tools of Scientific Revolution.

In technology every human culture, the hand and the brain work together to create the style that makes a civilization.
