I mean, let's talk about the fear around zeppelins. Zeppelins were used to bomb Paris in WW1[0], which wasn't that effective overall. By the time WW2 rolled around, we have the bombing Zeppelin 2.0 - the long range strategic bomber.
So I suppose what I'm saying is that, when people said "what will we do when they start using these huge flying things to attack us?" The answer was, "Nothing, your city is going to be destroyed." So maybe use another example of, "old FUD," because it seems like the people worried about Zeppelins were absolutely right. :)
It seems to be rare, especially when it comes to new science and technology. Sadly, with the military being such a large customer in these fields, we do end up with a lot of undesirable tech. The most effective way to reduce it is cut it off at the source (i.e. reduce military spending).
This sort of Technophobia has been around since the beginning of civilization.
Instead of focusing on the FUD, we should try to focus on the good.
