Dan SimmonsOnce upon a time ... the only autonomous intelligences we humans knew of were us humans. We thought then that if humankind ever devised another intelligence that it would be the result of a huge project ... a great mass of silicon and ancient transistors and chips and circuit boards ... a machine with lots of networking circuits, in other words, aping-if you will pardon the expression-the human brain in form and function. Of course, AIs did not evolve that way. They sort of slipped into existence when we humans were looking the other way.
