Well, why should it? No one is inventing HAL-like AI anytime soon, or ever. If this system does a better job of killing the enemy than human pilots then its quite the breakthrough. Projecting air power is one of the ways countries keep aggressors away and this would be quite an advantage for variety of reasons. Not the least of which means you can now design AI driven fighters that have zero design compromises to keep human pilots alive.
I imagine fighter engagement consists of a fairly limited set of problems to solve. Think of this as just a souped up autopilot/autoland system, except with guns and missiles. We're not asking the AI to write the next Romeo and Juliet here.
>because the paper is very light on details
Defense contractors aren't known for sharing details. I imagine this is a competitive advantage and they want to keep their cards close to their chest. There may even be national security issues here.
