If the human race does not destroy itself in a senseless war, and if our planet is not struck by an asteroid or afflicted by some other worldwide disaster, I think our race should continue to advance mentally. One big obstacle facing that advancement is the way that human minds are becoming lazy because of all the technology that is available to perform tasks that people used to do mentally, such as basic math. I’m afraid that this is causing our minds to atrophy to some extent, and that this could be carried forward genetically to future generations. Conceivably, we could become dumber as we rely increasingly on technology—and that’s where an important Frank Herbert prediction could come to pass—humans enslaved by thinking machines. But ever-advancing technology, and medical research, also hold the keys to exploring and mapping the human mind much more than we have done so far—and to finding ways to improve human mental functions. For human beings to resemble the Mentats of my father’s incredible Dune universe, these human minds would need to advance organically, and not through implanted technological devices.
