It is not a non sequitur Lou; an obviously tongue-in-cheek exaggeration of reality? Of course, but not non sequitur. How we educate or, better said, fail to educate both ends of the innate spectrum and prior competence/current willingness-to-study-seriously spectrum is an abomination. In a well-run, grade-level standards environment, simple grade advancement along with proper initial placement and a ready willingness to retain another year (or half-year if the school is large enough to make that workable) would be a huge step in the right direction. As a deep believer in the appropriateness of proof-based Euclidean geometry for an introduction to deductive logic and proof, its removal for all students because it's hard is an abomination. It took about 2500 years to kill Euclid but we finally got the job done.
On the topic itself, who cares? As usual, Bob has it right. Implications for the teaching of mathematics? Essentially none; same as we do in kindergarten for eventual artists, athletes, and other things we value. It is unfortunate that mathematics doesn't get the same "discrimination" as students develop; we miss far too many even though a solid math base greases the skids for later academic success, even in non-math disciplines, more than almost anything else. Failure to develop a solid base in math-based disciplines? Statistically speaking, they're doomed.
