The Blub Paradox is basically a rehashed version of the Sapir-Whorf hypothesis, and suffers from the same problems. In short, concepts aren't tied to specific languages. Norvig's expertise doesn't arise from the languages he's learned, but the problems he's solved with them.
This is demonstrated by the fact that Jeffries, despite his presumed lack of exposure to Prolog, was able to conceive of a solver that used constraint propagation. The problem was that his incremental methodology made him shy away from actually trying to build it.
