So researchers are going to be irrational and also often value other things more highly than prosociality but that doesn't really refute my point that they value it more highly than the average population.

Also your example of a bad technology is something that allows people to still communicate in the event of nuclear war and that seems good! Not all technology related to war is bad (like basic communication or medical technologies) and also a huge amount of technology isn't for war. We've all worked in tech here, "The development of technology is simply due to the reality of nations being in a constant arms race against one another" just isn't true. I've at the very least developed new technologies meant to make rich assholes into slightly richer assholes. Technology is complex and motivations for it are equally so and won't fit into some trite saying.
