Why can't Ace AI beat Ace humans?

[Sita]

at first i must say that make AI equal to Human is very difficult task ..even if we talk about only Il2 ... you can make AI pilot incredably accuracy shooting ... with very argessive and clear acurate manuvers .. but you can programm some unexpected actions from live pilot.. some improvisation ... some not ordinary steps in flight and fight...
so i suppose hard to say what's the matter .. matter in software or in programmers...
