Is it Hayek?

I believe that what we’re looking at is people who know their math, but don’t know what it means: they can grind through the equations of their models, but don’t have any feel for what the equations really imply. Confronted with informal discussion that’s grounded in models but not explicitly stated in terms of math, they’re totally baffled. And so they lash out.

It’s Paul Krugman.

And obviously, it’s not Friedrich Hayek.  Despite how tough Hayek could be on the almost universal misuse of mathematical models by academic economists, he never got personal, and was never rude or belittling.
