Some of the creative-version of "smartness" has already been squelched due to a growing focus on test-taking. This trend is furthered by college admissions based on test-scores and excessive AP class expectations. Art and music have largely disappeared from the K-8 public school curricula. In our terror of having lower math/science test scores than other countries, educational policy wonks have lost their focus on real education.
Additionally, one side effect of pushing college-level material down into high schools is that boys, with their 2-3 year cognitive lag, are at a huge disadvantage and are now under-represented at universities. We need to restore age-appropriate learning and critical thinking in our educational process and figure out a better way to evaluate progress.
Some people really do require ritalin-type therapies to become educated or hold a job, but turning every child or adult into a ritalin-driven robot is madness. Adults who choose to self-medicate in order to function better may find an advantage in the short term but the long term risks/rewards are unknown.
