Take self-driving vehicles. Every single piece of technology used in its development could be used with some minor tweaking in a military application to massively increase the lethality of existing weapons and allow for an unprecedented level of increased killing and destruction. But instead of selling themselves out to a future that will be remarkably more dystopian if given in to military application, Google has chosen to make commercial self-driving vehicles which not only will likely save an innumerable amount of lives by preventing fatal driving accidents, but also will be making boatloads of money at the same time!
Technology is a force multiplier for better or worse, and it’s up to us as the future engineers and scientists who will be creating this technology to choose the right path. For those sociopathic leaning people who could care less about avoiding a future of death on an unprecedented massive and automated scale, luckily that path will be no less lucrative.
