HOW FAR CAN WE EXPECT the development of the computer to go? What paths will future evolution take? To answer these questions we should consider both refinements in existing technologies and completely new device principles. The pace of computer evolution so far also leads us to think about the ultimate limitations of the information‐handling process, which inevitably depends on the number of real physical degrees of freedom available.
