At the heart of this ongoing discussion of the inevitability of self-guided murderers is the notion that the tech exists—it's just a matter of deploying it. A robotic anti-air turret, the kind that can acquire and fire on incoming missiles and aircraft without operator intervention, malfunctioned in 2007, killing nine sailors. Couldn't that happen again, on purpose? Sure. It's technically possible. But it's also as completely unlikely as North Korea dropping a nuke on U.S. soil, ensuring its own annihilation. No offense to the vast missile defense industry that's used North Korea to justify its post-Cold War funding, but capability doesn't equal reality. If we don't apply logic to the world around us, then we're either buying into someone else's hype, or simply terrorizing and distracting ourselves with phantom threats. The prerequisite for LARs to be used would be the combined lunacy of hundreds, if not thousands of politicians, military personnel, and researchers. Government shutdown jokes notwithstanding, the halls of the Pentagon aren't a crossfire of Three Stooges-style pie-throwing idiocy, nor is it stalked by ghouls desperate to find new ways to rack up collateral damage. Even if the most cartoonish version of the DoD is real, and it's dumb enough, and/or evil enough to make feasible its reported quest for LARs, shouldn't we wait for the first actual announcement or field-test of such a system, instead of preemptively shrieking at Terminator-sized shadows?
