The Danger When You Don't Know What You Don't Know

Gödel's theorem in particular lends itself to this sort of thing. For more mathematical schadenfreude, I like Franzen's "An Incomplete Guide to its Use and Abuse" http://www.amazon.com/Godels-Theorem-Incomplete-Guide-Abuse/...

Hackers will be interested especially in the rather weak attempts to use Gödel to make all sorts of silly inferences about artificial intelligence and the nature of mind.

Probably no scientific result of the 20th centry, except maybe the theory of relativity, has been used by so many to prove so much while understanding so little.

You are right, he is wrong. All abstractions and metaphors are leaky.

Was there something else?
