I must disagree with this characterization. Vinyl media was viable because tapes were not always necessarily an improvement. A poor quality tape deck with high wow and flutter is inferior to a record player. Your point is only salient in the days where technology progressed in price but regressed in quality.
Take VHS for example. Technologically, VHS was a regression over what was available before it going back almost 50 years. Film from the 1930s and 1940s (and perhaps even the 1920s) produce a picture superior in quality in an order of magnitude over VHS. But the technology that was necessary at the time was geared towards the mass adoption of recording capability. Magnetic tape was the way to go.
Optical media is not comparable in this respect. Optical media is far, far more reliable than silver nitrate film, and there’s no reason why a quality CD, DVD, or bluray disc couldn’t be read in 100 years from now. The limitation is only the availability of the technology to read the disc in the future, and not per se the degradation of the existing media, as is the case with other formats.
You can’t use HDD as an example to prove ODD obsolescence. HDD is a dynamic backup medium. HDDs have moving parts. Bearings have grease in them, grease deteriorates, and then the bearings screech and give out. HDDs are dynamic in the sense that they require constant supervision. You use a RAID 5 array because you get double redundancy. You have IIRC room for two drive failures. Optical media is a permanent storage medium.
Also, sure, it’s nice to have a nice big HDD hooked up to your WLAN, or an assortment of memory cards with your favorite films or videos on them. But watching video entertainment has often more to do with whimsy than it has to do with convenience. I can go on for years without opening something that’s very desirable to watch if it’s stored on the aforementioned media type, but when I have it on a shelf, in a DVD case, with a professionally printed DVD cover, it’s a whole different story. It’s a lifestyle enrichment.
People are dumping their old equipment because they arrive at this fallacious logic. That’s fine with me. I bought a very nice high-end Panasonic bluray player (no UHD support - I don’t need 4K), and I use that for my blurays and I have a seperate DVD player that I use in order not to wear out the Panasonic player too much. I’ve recently also invested in a bluray writing/scanning setup, and I’ve learned a lot of the technical specifics of writing and scanning quality blurays. I am more than certain that this investment will more than pay for itself in the future.
