You mentioned knowledge as being potentially infinite. It’s very important to emphasize that knowledge is a distributed and collective phenomenon. I go back to this wonderful little essay that was written by Leonard Reed in the 1950s called “I Pencil” in which a pencil works out how it came into existence and discovers that millions of people contributed to its manufacturer—from people cutting down trees for the wood to people mining graphite for the lead. The important point is that not one of them knows how to make a pencil.
