Digital is like the invention of sound, 3D is like the invention of color. Sound changed everything in movies while color made it better. Just like when you see a 2D movie you’ll feel like you’re watching a black-and-white film. Ultimately everything will completely be in 3D.
Sound isn't better than silent, colour isn't better than B&W, and digital is not better than traditional. They are different mediums, but they are equal in every way, with their own particular strengths. All should coexist, with one never being discarded in favour of another.
