visionary

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.
