If they can "interpolate" existing data to that level then saying "just don't hack" doesn't make any sense, hacking is derived from knowledge of software systems. It's far harder to solve navier-stokes than creating a program that replicates and abuses computer resources.
You could as models improve continue to remove more and more training data, what happens when there is no more data left to remove but a running system still outperforms humans? I think you grossly overvalue data.
