Technology depends on a lot of people cooperating around the globe. Disrupt a few critical chains (power generation, fertilizers, computers), add a bit of good old war and you'll soon be in the era before Haber process and a lot of people die. And then the remaining people will have trouble keeping that level of technology with how sudden the change would be.
Well yes that's what I said, it could destroy civilisations and their technology. It seems much harder to kill every isolated tribe in the whole world, and every survivors of the destroyed civilisations.
