Tough to say. Without World War 2, would Radar, Rocket technology, and Nuclear fission have been created? The thing about war is it to the test human ingenuity, and is one of the greatest incentives for innovation. The technological advances created in a fury of R&D during wartime find incredible civilian applications once we've stopped using them to kill.

No.
Wars create scientific progress as government is willing to spend more.
US would have never gone to moon without the German scientists from WW2.
Ultimately every single piece of advanced technology we use on a regular basis was a result of WW2, which was a result of WW1.
Computers, phones, games, all resulted from progress made during WW2.
Without those wars we would not have made so much progress.

No, war is the mother of al creations.

Technological advancements happen roughly 3 times faster in a time of war than they do otherwise.

Necessity is the mother of invention; war creates necessity like nothing else can.
