Earlier quoted context omitted.
The setup makes it impractical. You would need a very powerful computer to run it in real time. And it won't tell you about what u can't see. You would need to do the same for audio and game mechanics. Check what a top player can do: https://youtu.be/8Qf5Xlty1Cg I doubt an AI will be anywhere close in the next 10 years.
The AI doesn't have to play the game, just recognise enemy players and calculate how many pixels to move the mouse so that you are aiming at their head. Even the top player you showed could probably have improved his run quite a bit if instead of having to aim he got a guaranteed headshot every time he fired his gun in the vicinity of an enemy.
That's where anticheat is going imo: algorithmiclly defining what the fastest more precise human should be capable of. Anything beyond that is "cheating".
