Do we really want to "reduce such a beautiful and meaningful art form to something so mindless and trivial[?]; no culture could be so cruel to its children as to deprive them of such a natural,satisfying means of human expression.

"One of the best ways to stifle the growth of an idea is to enshrine it in an educational curriculum." - Hal Abelson[2]
