I read waiting for one item: longevity. My concern is that the digital community is in a fantasy world if they think continuous re-mastering will = continued longevity. That is un-proven and indeed can't be proven. 80 years from now an important digital photograph of JPII in repose is re-mastered for the 16th time but all of the subsequent losses have finally had an additive effect so that the data is meaningless. Interesting point about NASA. Interesting also that the library of congress is recording musical sounds that define our era on 78rpm shellac. Heartbreaking that the patent office has gone the other direction and thrown out old hardcopies wholesale.
