visionary: n. 1. One who hacks vision, in the sense of an
Artificial Intelligence researcher working on the problem of getting
computers to `see' things using TV cameras. (There isn't any
problem in sending information from a TV camera to a computer. The
problem is, how can the computer be programmed to make use of the
camera information? See SMOP, AI-complete.) 2. [IBM] One who
reads the outside literature. At IBM, apparently, such a penchant
is viewed with awe and wonder.
