Should that truly be the end of the analysis for a thorough, intelligent person? Is that where good, intelligent analysis SHOULD stop, (i.e. "it's effective and has saved lives" end story, end of evaluation, I don't care what happens beyond that, but it's certainly effective when we're looking two feet ahead?)?
Should we also want to be reasonably certain that it won't do any harm in the long term? Is that why we typically have VERY long testing and assurance cycles for new drugs and treatments??? Is that a best practice that has been established and managed by the FDA and scientists, researcher and doctors in general???
If you eliminate this best practice, you run the risk of achieving a Pyrrhic victory, correct? One step forward in the short term, but two steps backwards in the longer term, (which is a NET loss). Now, of course, we don't believe it will cause harm, and we certainly HOPE that it won't cause harm, and there are no ostensible indicators that make that seem likely, but when we start denying the possibility, and acting as if we haven't taken on more risk by cutting out such super important best practices, it's scary, because we aren't operating scientifically, or operating in truth.
