That's ridiculous. You're comparing apples to oranges: using Haskell and
understanding the underlying theory are two completely different
things. Put it to you this way: a mechanic can strip apart and rebuild
an engine without knowing any of the organic chemistry which explains
how and why the catalytic converter works. If you work for Ford, on the
P.S. I did my computer science graduate work in type theory, so I may
not be an "average Haskeller" in those terms. By "garden-variety" I
meant to say that the concepts, notation, and vocabulary are pretty
standard for the field, and I had no trouble reading it despite not
having seriously read a type theory paper in close to a decade.

Introductory type theory is usually taught in computer science cirricula
at a 3rd or 4th year undergraduate level. If you understand some
propositional logic and discrete mathematics, then "probably yes",
otherwise "probably not."
