Dennis Bushnell, former chief scientist at NASA Langley, was one of the most intriguing characters I had the pleasure to work with during my years in scientific and technical intelligence. He had many ideas, I'll leave it at that, but he was always so fun to talk with. I just looked him up and found that he retired a year after I did and died about a year ago. A sad loss. He was extremely driven and dedicated to his career and really enjoyed working with colleagues in the IC. Here is a slide deck of his musings which according to his Wikipedia page was produced "circa 2025" (which I'm not sure I believe because this was 2 years after his retirement and the year he died, he was 84 and would not have been using NASA template after retirement I think?) But anyway, to give you a sense of Dennis Bushnell ... https://www.metabunk.org/attachments/future-strategic-issues-and-warfare-pdf.3295/ RIP.
