If you're pro-war and support this kind of shit, you should know that every fight has two possible outcomes: you can win and you can lose. This is the same reason you don't wanna be a police officer or go to the military if you're not ready to die. After all the pain people have experienced in eastern Europe, Gaza, Middle East, it's sad to see this has been funded by YC.
It's pretty obvious it's the same "defense" system as AK-47. While it's easy to justify, it will be used, highly likely, to kill people.
