But the digital miscellany we're building for ourselves is an over-abundance of likenesses, across every domain. The likenesses are drawn by every link we create, each made of intention and meaning.
It's true. In the past, if we wanted to shift domains, we had to cross town or campus to move from, say, Russian literature to biochemistry. Now we can do it with a click. And what's more, biochemists or nuclear engineers with blogs can dip into Tolstoy or Kundalini yoga, and do mash-ups themselves. We're much less boxed in by domains. They have digits, cells and molecules in common. And much of the discovery and innovation today, whether it's in quantum dots or Nintendo's Wii, comes from mixing one domain with another.
