The future of AI as a military tool is, under some conventional wisdom---thought to be over blown.
But at least some AI researchers are concerned---and this short film, released before the UN Convention on Conventional Weapons, which is coming up---argues that there should be some constraints before the technology runs amok.
Some weapons conventions (sort of) work; biological, chemical, and nuclear weapons have not, on a world-wide basis, been used a global conflict since WW-II. Regional and even worse, intra-state civil wars---that's a different matter. So maybe, some agreements to limit military AI might be helpful.
It's a bit unsettling; a fleet of drones with a 3 gm copper penetrator and a very refined version of Apple's Face ID sensor and software---hunting through a city; and then they run out of battery, self-destruct and release the next 500.
I dunno; not an engineer. Someone tell me this is ridiculous and will never happen. Although Elon Musk seems a bit unsettled.
BTW, the batteries comment because: short flight life. But if you could solve that...and increase loiter and flight time.
