This seems to be an unnecessarily disparaging view of fuzzy logic. It may
not be particularly deep from a theoretical point of view, but this does
not prevent the idea from being successful in engineering applications.
The Wikipedia article is a pretty good introduction to the subject,
listing some "practical applications" as well as clearing up certain
misconceptions. In particular, until I see some more historical evidence,
I'm quite skeptical about any alleged historical connection between fuzzy
logic and ultrafinitism.
