In 2020 the Defense Advance Research Projects Agency (DARPA) funded over 220 million dollars in Math and Computer Science Research (DARPA Budget). In my field (Applied Category Theory) the best funded research programs are funded by either DARPA or the Air Force. At first this seems kind of baffling. Why does the Air Force care about using homotopy theory to find an alternative foundation for mathematics? Why does DARPA care about the properties of colored operads? Many mathematicians give them the benefit of the doubt. If the military is interested in funding projects which seem to just enrich mathematics as a whole, then maybe their intentions aren’t so bad. This is a convenient explanation, made more convenient by the high paying jobs and hefty grants that the Department of Defense (DoD) offers. Unfortunately, my personal experience has shown me that there is no truth in it.
The DoD’s real goal is not just the math you produce, they want to gain access to your mathematical community. Maybe you would never work on missile guidance systems. That’s okay, the people you work with at the DoD will gain expertise in your mathematical specialty. They will present at conferences and find new collaborators who will have more flexible morals than you.
Your math is not too abstract to be useful. The DoD wants to build themselves into these mathematical communities from the very beginning so that when it does eventually become practical they will be poised to take advantage. If it takes a longer time to become practical then that means the DoD will have enough time to become entrenched into the foundations of the subject.
The DoD wants to normalize themselves in your non-mathematical communities. Since 2001, over 800,000 people have been *directly* killed and more than 37 million made refugees in the US post 9-11 wars (https://watson.brown.edu/costsofwar/). The DoD wants US Citizens to be okay with that and the best way to gain an ally is to go in business together. The DoD wants to demonstrate that they can put food on your table and advance your interests so that you will turn a blind eye to the violence they commit abroad.
The DoD will lie to you. A friend of mine worked for a project whose public goal was to provide technology for search and rescue operations. However, in more private conversations the terminology slipped from “search and rescue” to “search and destroy”. None of the researchers in this project or their collaboraters were made aware of this. The DoD is under no obligation to tell you the true motivations behind your grant or job. Sometimes these motivations are classified.
As conditions in US worsen, I think one of the best things we can do to heal the world is to stop doing things that make it worse. I personally do not plan on collaborating with DoD funded mathematicians and I hope you will join me. If Grothendieck knew what his math was being used for he would roll in his grave.
