Well yes. Plenty because even one human is plenty. But plenty compared to how many people died in WWII? Or WWI? Or any real war we had before?

Compared to what happened immediately before, the cold war was incredibly peaceful.

So I suspect this new cyber war will continue the trend and keep real killings to 0. I do believe we will have a real internet hacking and protecting and counter hacking "war" if you will. But I suspect, and obviously hope, no one actually dies from it.
