I think I understand his viewpoint, but I feel he is displaying a small form of insecurity or fear.
Nothing lasts forever. Yes, certain media will let it last a hundred or so years, but they do degrade slowly over time. I doubt the original film negatives will give you 50 years without becoming so brittle that they are destroyed if handled after such a long time as well. Tangible? Sure, but not for long. Then where are you? In the digital world, we also have a time limitation (the life of the media used), however, in the digital world, there are no generational losses if reproduced or copied. The potential of extending life is easily there without loss. This is simply not an option in the world of tangible film or glass... unless you come into "our world" (lol).
Though I am not a shooter of a lot of film, I *love* film. I've seen some things on film that even the most advanced and expensive cameras on the planet today cannot come close to... but, anyone who feels that this initial tangibility is anything more than a temporary fix compared to the intangible limitless life of digital... I kinda think that they are walking around with a little set of blinders.
In the digital world, I can *choose* to print things out and have that tangibility, anytime... but in the film world, anyone that wants the advantages of digital (ie: reproduction with ZERO generational losses), will have to digitize to be able to further extend the life of that picture without further degradation.
