And regardless, is there even value in having autonomous fighter jets when we already have advanced missiles? It doesn't matter how good the pilot/AI is if they are just firing missiles from miles away. We already have missiles that can loiter for hours before choosing a target and attacking it (ex. IAI Harpy) - to me that is much more valuable and dangerous than an AI fighter.
Army of None: Autonomous Weapons and the Future of War is a good book to read about it.
