You know that vinyl is not the only way of recording analog information, right?
There is also cassette tapes, reels, wax cylinders, laser discs… Analog supports degrade over time. Digital files do not.
Digital storage devices have way shorter lifespans than analog ones. Digital information can be more reliably copied, but we are constantly losing massive amounts of information to digital storage loses when it falls out of public consciousness. If no one is actively copying it, it is doomed in the digital age. We still have analog storage that’s good enough to be useful from thousands of years ago.
The analog storage you are referring to from thousands of years ago has degraded substantially since its creation. Yes it’s still useful but I wouldn’t use that as evidence it’s a better medium. Case in point: texts (a digital storage form) from thousands of years ago can be retransacribed to be exact copies of the original (with respect to the knowledge contained within of course) whereas paintings from the Renaissance have changed dramatically due to aging and can never be returned to their original form since the needed data is lost.
Digital files have checksums. You literally know when something has changed and you lost information. And then you have error-correction on top.
