I think that's the problem he's pointing out though with medicine: that we're unable to account for all the side-effects, that our hypotheses are often wrong (in drug development, its practically like a lottery if you start at pre-clinical), and that these gambles on drug development are getting way to costly for the healthcare system.

I think there needs to be revision of the experimental method overall, as the models of drug development in the 20th century simply aren't sustainable or efficient for the diseases of the 21st century.
