..but I know that the scene there is nothing, but great and clever use of artwork and shaders. There is no A.I. or other advanced programming, at least I didn't see any. Tell me if I'm wrong.
No, you are not wrong. This might be true. I also don't see AI and such. But you missed the topic. This is not a game. It is a video of an unfinished demo.
Just ask yourself is there any advanced AI in the official Conitec warehouse demo or in the venice demo?
