Hmm . . . nobody jumping on the statement?
As some may have noted I tend to like understanding aspects of technology especially older technologies . . . their advent in society is directly related to use of such technology but to a large extent advancement is determined by the inability of society as a whole not understanding the technology.
So I should perhaps make further explanation of the stated view? . . . relating it to the computer or perhaps the automotive industry might be helpful. A simple statement that as digital technology replaces film, it is directly related to the computer industry . . The greatest aspect of PC usage is that (Windows) programs require little knowledge computer languages (programming). So as the automotive industry, one doesn't require skill as a mechanic (knowledge, tools & interest) to own or operate an automobile. A similar statement can be made about photography.
My sister showed quite a flair for photography in her youth. I have some of her old work done with her little Browne (Kodak) camera. She showed a real potential but the desire was not there.
This I learned a few years ago when at a family (holiday) dinner, she approached me with her disposable point & shoot (35mm.) camera to take some photos for her as she was busy with preparations for the meal. when I dropped off my film, I dropped off her camera. when I pick up the photos, I was astounded to find that several holiday's were among her shots . . . probably spanning more than one year!
Thus the implication that to advance a technology one must promote an interest in usage (consumer interest) & readily usability by inexperienced (novice) consumers.
