"What was considered dangerous in the past is today made possible with advanced technologies." What was considered dangerous in the past is dangerous today. It is what was not considered dangerous in the past what we know today it is dangerous, like x-rays(they used it with pregnant women and basically killed a lot of people for ten years), powerful RADAR, tobacco(yes you can see advertisements on youtube of how innocuous it was), benzene, asbestos, pfcs, nuclear radiation(Curie couple died from that). It was only after being proven that a technology kills thousands of people, that this tech is controlled. For me it is a great idea to find guinea pigs for testing new technologies, but don't test it with me against my will sending radiated energy in the air.
