AI scales better to how many jets you want to use. AI improvements can also instantaneously be rolled out to every jet. There is no need for continues live communication in "hot" combat. Less video leaks when they kill a bunch of civilians again.

Also think about the export market! Countries that now can buy the ruthless-pilot with the plane! And like with so many exports, you can give them a shittier version of the AI, so they do not become a danger to your forces!
