"Technology is really aiding navigation, but I think it's actually reducing our sense of place. You don't need to know anything about a place to navigate through it."

"There's one best place for every piece of type on the map relative to the others. You change one thing and everything else changes. It's an incredible orchestration that takes a long time to work out."
