I didn't watch the complete and don't know how good is AI of this system but its actually pretty common for ex as well as in-service pilots to practice against AI in simulators like DCS and BMS,in PAF as well and I have seen them getting beaten by the AI.
But there are many factors to this:
1)Pilot not being used to simulated environment.
2)Head tracking is a major issue for the pilot (in case of VR,it causes motion sickness)
3)AI has no fear factor
4)If pilot executes an out of the book maneuver,AI will be dead in no time.
5)As
@PanzerKiel mentioned,no Gs involved for the AI.
6)A pilot being a pilot,when flying in a simulated environment,he will still be keeping an eye on his expendables such as fuel,ammo,counter measures etc.As well as aircraft's limits such as G limit etc.Al is free from all these distractions,it will consume everything it has and take advantage of the fight or crash at the end if goes bingo.
7)In BFMs,AI's accuracy will be much better (and of course this is what makes AI better than Human)
8)In a 1 v 1 BVR scenario,AI will go cold as soon as a missile is fired on it and stay cold until the missile dies while human has many options in this case.Also human pilot wont know he's been fired at until missile goes Pitbull but AI (most probably) will know he has to go cold as soon as a missile is launched.
And many more..
I have always been against a Real life pilot v AI pilot.A person who has been flying aircrafts his whole career cannot be accustomed to a simulated environment in just 2 missions,as soon as he starts pulling the stick,his mind will start working as he's in a real jet and not a Simulator.
If the goal is to study Human v AI then maybe a Simulator used person v AI might be better, flight simulation community is full of people who have been flying combat simulators since last 20 years.
