We've heard about this and that. But I actually went back and took what I could find, the examples in history where there have been prohibitions against technology, and then I tried to find out when they came back in, because they always came back in. And it turns out that the time, the duration of when they were outlawed and prohibited, is decreasing over time. And that basically, you can delay technology, but you can't kill it. So this makes sense, because in a certain sense what culture is, is the accumulation of ideas.
