I'm asking from a sociological perspective here.
Motivation: I wonder if it is true that technological development is better during war time, and if so, why? Is it because the review process is different/faster? Is it because people are forced to work together? Forced by whom? 20th century history has had some "geniuses", but then again it seems that these people might just have had the advantage of being brought together (e.g. in the Manhattan project, where Feynman gets to meet Von Neuman).
I don't think I'm the first to make this conjecture, and so I wonder if there have ever been people making this point to support a pro-war agenda.
