hello friend, I find this video extremely interesting, I really totally agree to a certain level of this type of progress, and even more for military use, due to the minimization of casualties on the battlefield, ideal for the fight against terrorism , far from what you say, which is obviously designed to harm people, is also designed to protect them from this type of acts, and that is why I give my vote in favor of this type of technological development, but leaving this context , imagine that the damage that could be done to a defenseless population, in the hands of the wrong people, would be a real catastrophe against humanity, should have extra prevention controls with the developers of this type of technology, to keep the civil population really protected and both physically and psychologically, very good video.
