The picture reminds me of 1951's Arthur C. Clarke classic short story "Superiority".
The ultimate cause of our failure was a simple one: despite all statements to the contrary, it was not due to lack of bravery on the part of our men, or to any fault of the Fleet's. We were defeated by one thing only - by the inferior science of our enemies. I repeat - by the inferior science of our
enemies.
