What does weapons research have to do with my comment? I would rather see my tax money go to things like Alzheimer's/cancer research and public health measures. I'm not against people researching stuff like the eclipse in the Odyssey for fun, but it shouldn't be publicly funded, especially when the premise of the paper makes so little sense.
