The New Yorker looks at the trend of neuroenhancing drug use among people looking for an intellectual edge (adderal, modafinil, et al). This pairs well with the Nature piece from last year: Towards responsible use of cognitive-enhancing drugs by the healthy (pdf)
If additional research shows that they're safe for long-term use, I don't have a problem with the idea of cognitive enhancement. (better living through chemistry?) It's not conceptually different from the caffeine use that already pervades our society.
