This video is fictional, and was made as a warning about where current tech could take us. I have no doubt that generals who have seen it are quite upset that they can't have it yet.
Thanks. I thought I had found the original upload after sifting through a lot of copies on youtube. Wish youtube was a little proactive with detecting dupes, rather than reactive. Or at least some sort of an automatic note/link to original even if it is a legal derivative.
As far as I can tell, this is the original: https://www.youtube.com/watch?v=9CO6M2HsoIA
