The story of Aum is as strange as it is tragic, but it serves as an important reminder about the ambiguity of scientific advancement and the democratization of high technology. Although scientists pride themselves on their objectivity and ability to stick to evidence, Asahara demonstrated that they are just as susceptible to being lead astray as anyone else. Moreover, as the cost of sophisticated technologies continues to decrease, it becomes easier for bad actors to get their hands on these same technologies and use them for destructive ends. In the age of deep fakes, gun-toting drones, and freely available militarized malware, the next incarnation of Aum might not be so easy to stop.
