>Will X even work? Why is this so often a question for things that are clearly possible? If this or that particular method doesn't work, well, ok, but I'd find it hard to believe that never in history would people be able to spread genes through a population. Computer viruses, cloning, facial recognition, atomic bombs, genetic engineering, cryptocurrencies. These are things there were weakly (or un-) regulated until they came into existence. Now, you might ask yourself if jetpacks might be a socially viable for of mass-transportation, not if they are technically possible. Years are wasted asking if something is possible before preparing for it, and precautions and regulations are created post-hoc by lawmakers for stuff that was sure to come. Does anybody know of a good "turned out to be impossible" situation?
