What if intelligent computing were centered inside humans? Portending an even braver and newer world, it's now possible to insert wires into a person's nerves to control appliances. We can even send such signals over the Internet, where they are decoded by computer and then fed into another person's nervous system. Human bodies are getting more and more plugged in. It's not easy to set aside questions of ethics and choice. It is not even possible. However, in this essay we simply overlook them in order to work toward our hypothesis. To do that, we must take you on a trip into space. Our argument is that if humanity decides to continue human exploration of space, we will sooner or later-probably sooner-be forced to center some intelligent computing inside humans.
