And that's not a counter-argument. Or do you really believe that 2001 could be made today, as it was then?
One of the reasons I like Christopher Nolan films is that he goes out of his way to actually make stunts realistic. In Inception, he actually built the hallway on a gimble and tumbled his actors. He built a second hallway vertically and suspended JGL from wires. He actually had a train drive through a city street (albeit, not a real train, a fake one, and he used CGI for the torn up asphalt). In Dark Knight, he actually flipped a frickin Semi truck. The Batpod was a real working motorcycle.
Anyhoo, I think that there are directors who could make 2001 today.
