This is a tricky topic.
You would also have to add to menagerie things like swing music being developed in the 20s; a time of peace.
Further, this post doesn't really address innovation, it talks about implementation. It is what happens after the inventor has the flash if inspiration. After that, many of those inventors live quiet, desperate lives of not enough material inputs to get it developed.
There is a huge gap created by capitalism. What the investors want is something that is one step away from being marketed. They don't even see, most cannot even imagine, what an invention may look like in several iterations. Further, capitalism puts a blanket over everything. Keep it secret else someone else will steal it.
And so, another piece of war time is that we all have to pull together to win the war, is the motto, so the information is tried to keep secret from enemy, but is much more freely shared.
I believe the internet free and open source community will destroy the idea that war is the best times for innovations. I am looking forward to the future.
