A mind that stays at the same capacity cannot live forever; after a few thousand years it would look more like a repeating tape loop than a person. To live indefinitely long, the mind itself must grow, … and when it becomes great enough, and looks back … what fellow feeling can it have with the soul that it was originally? The later being would be everything the original was, but vastly more. —VERNOR VINGE The empires of the future are the empires of the mind. —WINSTON CHURCHILL
