The safeguards and caution are even more immoral from a rationalist point of view. By delaying potential medical breakthroughs you cause many future humans some amount of additional suffering because medical breakthroughs build on one another. If you delay an ALS cure by one year, you are not only harming all those who have ALS for that year but all those present and future humans that have other diseases that could benefit from the future research tree branching out from that ALS cure. Suppose for example that our ancestors were more risk-averse, more focused on the moral "do no harm" and thereby agreed upon 20 year trials for all new surgical procedures. What would 'modern' surgery look like? We should be celebrating the risk-takers as willingness to take an experimental drug or an experimental treatment as it is often a greater gift to humanity than an organ donation.
