The most impressive new technology is often the result of massive spending by entities far more powerful than myself.
Guns are technology which can directly kill me, but I'm not too worried about guns, or even must gun owners. But when you're talking about a technology that (due to massive cost) is only available to governments with questionable oversight, that gets worrying.
In this specific case, I'm not particularly concerned - but you can see how the availability of the tech in question matters. If only people who are already more powerful than me can have it, it's much more likely that its power can be (ab)used to my detriment.
