Further to my review of Ghost Fleet a while back, I came across this interesting note on Motherboard.
Last year, the Naval Academy made two distinct changes in how it operates—one that’s a natural progression in cyberwarfare, the other a clear response to how thoroughly we rely on that technology.
“First, they've created a cyberwarfare center and created the first class of midshipmen who will be cybersecurity majors,” cybersecurity and military expert Peter W. Singer recently told me. “Second, they required that every midshipman learn how to do celestial navigation like they did back in the 1700s. We're preparing both for a world of cyberwarfare and, ‘oh my goodness, what if I have to go back to navigating by the stars?’”
I can imagine a situation where even a limited war in space or cyberspace ends up trashing civilisation because we've come to rely so much on this stuff. You blow up enough sateillites, for instance, and you can forget about launching any more for hundreds of years because it's just a debris field up there.
I probably should have made more of this in AoT.
