I'm optimistic that bad science is on the decline (at least in regards to smart drugs like Modafinil).
It appears also that the research institutions are figuring out that there's a tremendous public interest in Nootropics or smart drugs that can be used by healthy young people to make them happier, healthier, and more productive.
This indicates science getting more into the prevention and empowerment business as opposed to just being in the business of treating sick people.
