visionary

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.
