Randall Parker of FuturePundit comments on the latest figures for medical research funding: "I am not surprised that diagnostics and therapeutic devices [research and development] yielded the best returns. Drug development returns have been declining. Diagnostic devices are taking off in in part because of a shift toward miniaturized devices. Diagnostics are going to follow in the path of computer chips with smaller devices becoming orders of magnitude more powerful and at the same time orders of magnitude cheaper. ... My own take on drug research is that it is becoming yesterday's approach to medical treatments. Most remaining health problems can not be solved with drugs. We need cell therapies and gene therapies much more than new chemical molecule drugs. Most diseases of old age and the very process of aging will be cured by gene and cell therapies and not by drugs."
