Because it's not a technology, but an art-form?
It's like saying that painting is old-hat and only digital-photography can be done from now on - why would anyone "paint" or "sketch" or "draw"? God, what heathens!
No, it's like saying that digital photography with the first wave of digital cameras is more artful than digital photography with the most recent professional cameras. What the author actually means to say is that his "art" in working within unnecessary limitations to produce a very artful result is not appreciated by people who mostly think "that picture would have been much better at a higher resolution".
I read TFA (I know, I know) and the whole thing basically boils down to "good art is better than bad art, but most people don't recognize bad art". It has always been that way. Even more, most people these days will have trouble appreciating even the classic black-and-white movies, even though they know a-priori that it is art. Past a certain point it's very difficult to see past the outdated technological limitations.
