Brain enhanced productivity growth

From the NYT "'One person who posted anonymously on the Chronicle of Higher Education Web site said that a daily regimen of three 20-milligram doses of Adderall transformed his career: 'I’m not talking about being able to work longer hours without sleep (although that helps),' the posting said. 'I’m talking about being able to take on twice the responsibility, work twice as fast, write more effectively, manage better, be more attentive, devise better and more creative strategies.'"

Productivity is the single most important determinant of economic growth. Cognitive enhancing drugs such as Adderall and Provigil (and their improved successors) will soon do for our economy what electricity did for an earlier generation.
