The people in charge don't actually need to understand technology. This is what subject matter experts are for. You hire subject matter experts to research the technology in question and collaborate with them to come to a decisions about how regulations should be enacted. I don't know where we got this idea that someone who's job is legislation should be a subject matter expert on technology (or aerospace, or I dunno, fucking education, engineering or whatever), but it's actually a bad precedent we're setting because that's not what a legislator is supposed to be doing. Lawyers don't have to understand technology or medicine or fluid dynamics in order to practice law. They hire and utilize people who specialize in those fields.
