It's basically constant that many people will fearmonger and some will embrace new technology. I think this is basically independent of the actual merits and drawbacks of the given technology. Regardless of these strange asymptotes, I would say technology has been advancing from less benefit/risk to more in time, and so we will get closer to the fearmongerers being right. I suppose it could mean that we harness the benefits and waive the risks, but in practice it seems unlikely.
