I have beaten some of the most advanced AIs the gaming world has constructed, even ones that “cheat.” Yeah, I “died” a lot, but there is always a flaw you can exploit in the algorithm - even the “learning” ones (you teach them bad tactics then shift).
They may get there, but as for now put a 14 yr. old kid who has been gaming since age 6 - as opposed to some old guy like me - against the AI and the kid will shred it.
As you stated, you died a lot. What if each death cost you a 30 million aircraft? Can you afford to train it in bad tactics, and then switch? And what if that technique can only work at most one time, as the data can be transmitted back to HQ in order to train surviving aircraft to recognize that technique?
