The people who buy such software and don't return it.

It's a little more sophisticated than that.  There are CAPTCHA defeating
OCR programs that recognize letters distorted in ways they have never
previously seen before:

You need more than a simple look up table for that capability.

Sounds like what goes on when someone dreams in the dark.

It doesn't point out anything, it is an intuition pump (

people to an apparently obvious conclusion (if they don't think too deeply
about it).
