Did wars helped us advance in technology?

I would still argue that technology did advance at a higher rate during wars. Maybe not science, but technology and engineering definitely. During a war you have a lot of pressing issues that you have to develop solutions for quickly and a lot of stimuli as at time the very survival is at stake and also the time is of the essence. As a result there is a great push to solve myriads of problems as fast as possible and using as little resources as possible.

The science proper on the other hand would suffer a lot given that international collaboration and availability of resources of multiple international scientific institutions are important in order for the science to advance faster. All or most of these are not available during wars and financial/human resources are taken from scientific front towards technology.
