I agree with you. I know that and for this reason I am very interested in analysing film technology (as already I did for other tech). So please, reply to my questionnaire so that I can develop this (and forthcoming) research on this subject. If you want know about my studies about "old and declining" technologies, send me an email and I will send you some papers.
PS: FYI, my preferred product are my "old and declining" analogue turntables
