Prof-you are wrong in your analogy with cameras. Today’s cameras are so much better than just a couple of years ago. My iPhone camera is probably better than the 1 ansel Adams used. I had a Nikon d1 which was a $5000 camera 20 years ago and it had features than some of the newer cameras don’t have, except for 1, number of megapixels. The d1 had 3 megapixels, the new nikons have10x more megapixels. If you blow up a picture from a d1 past a 8x10, you get fuzziness and it looks like s---, blow up a 25 or more megapixels camera and you will see it as pristine. Same goes with cables, new technology has improved the sound quality and sometimes this requires paying more $$$.
