Not so dated
It is probably still far away from what we have, the Matrix was basically the Internet with a VR interface. They even had their "home location", as Case always appeared near the Eastern Seaboard Fission Authority, no matter where he was jacking in from. The only thing dated is the fact that it occurs a couple of decades after WW3 between the US and the *Soviet Union*. Orson Scott was able to sidestep on this simply making the "Warsaw Pact" the "NEW Warsaw Pact" in Ender's Game.
I would still like a Neuromancer movie, though some people might think it's a Matrix ripoff instead of the other way 'round.
