Remember the word "recalculating", you know, the word that your GPS feeds back to you when conditions change? Or the phrase, "lost satellite access"? Well, your target may move, but you are stationary waiting for system to unlock? If you pull the trigger, the gun doesn't fire until it reacquires lock on your designated target? So, the target moves out of the sight picture and you are left with a weapon just waiting to fire by itself? I bet they are light years away from replicating the human's ability to react to a changing tactical situation. Should make it easier for lieutenants at Quals though.
