As long as WWIII is a cyberwar of nerds hacking each others' systems, that seems like a big improvement over its predecessors.
WW3 would be too devastating. Something like Cold War 2.0 is more likely. Imagine sanctions on China, couldn't happen both our economies would suffer horribly.
If only war was completely in "cyberspace" and no one got physically hurt...
You really think cyber-warfare can't hurt anyone physically? What if they hack the 911 system? What if they hack the power grid? etc. etc.
Well, may not be physically hurt but a full blown cyber war does affect everyone's lives.
If WWIII results in mass extreme inconvenience I will be a happy man.
