I definitely agree. I'm very worried about the potential for a World War 3 scenario where not only has the warfare technology in combat, the weaponry and ammunition, the missiles and bombs and such becoming more precision and deadly components of war but beyond that the parties involved have the added digital technology, imaging technology, unmanned aircraft vehicle technology, and all the rest of the warfare-related tech that's cropped up over the last decade plus added to their arsenal.
In an all out war scenario we don't really know the extent this new technology will ultimately play. Is it going to be the type of scenario like the first two World Wars where rifling, tank, and air combat technology is going to be one of the deciding factors? Is it going to be something more akin to World War 2 where Alan Turing's work on deciphering of the Enigma Machines / Nazi's communication codes is going to play an integral role in preparation, troop movement decisions, and gaining the edge on the enemy?
I get the feeling, personally, that it's going to be a combination of everything above and more. Those individual military's capability of incorporating all of the tech at their fingertips and applying the knowledge / inferences gleaned while also making the best use of their cyber, hard, and soft military tactics is going to be a major deciding factor since the war will probably be staged on many fronts (physical and digital) between many allied nations versus many other allied nations.
The ability to communicate and execute will be as important as it always was (e.g. maximum importance, as usual) and I strongly feel that history will reveal the more technologically advanced and more wisely dependent nations of those technologies will write history as they become the winning nation(s) / powers.
