    Analog is inherently lossy due to the materials and playback method. Vinyl records sound different when they are dusty.

    Digital is inherently lossless because the Nyquist–Shannon sampling theorem guarantees that, given a sufficiently high sample rate, all information from the original signal is preserved.

      Your speakers are analog. They sound different when they are dusty. Your ears are analog. Things sound different when you have dirty ears. Nyquist-Shannon sampling theorem only applies when there are no frequencies outside of the sample range, which doesn’t happen in real life. None of this matters, because like I said it’s trivial to have orders of magnitude more accuracy than you need. Digital is just way cheaper to copy accurately, so that’s why it has become dominant, and that’s fine, but the idea that it’s inherently more representative of reality is just gibberish.

        It is inherently more representative of reality. Measurably so. Vinyl doesn’t and cannot have the same dynamic range as digital.

          You know that vinyl is not the only way of recording analog information, right?

              True, but analog cylinders are going to be the ones people after the world burns can find and still listen. I wouldn’t count any old CDs play at that point anymore.

              Like analog degrades, digital just stops playing.

              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.

                Digital files have checksums. You literally know when something has changed and you lost information. And then you have error-correction on top.

                  How do you think that is in any way even remotely relevant to what I said? If the drive your file is on dies and you didn’t copy it to another one a checksum won’t help you.

                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.

                  What makes you think we are perfectly copying the knowledge contained in texts from thousands of years ago? That is… a bold claim. Even if I were to accept that text is always inherently digital for the sake of argument, the storage medium is absolutely analog. You can use analog storage to store digital data just as much as you can use digital storage to store analog data like sound waves.

                    One example: https://en.wikipedia.org/wiki/Iliad?wprov=sfla1

                    Yes, you’ll make the argument that the available versions of it are not perfect representations, though that is only because the language and dialect used to produce the work had been lost, the work otherwise remains intact.

                    Text is a digital format because you have a limited set of characters to represent sounds/syllables. For example: the meaning of the letter ‘B’ doesn’t change if a small piece of the letter is missing or if the letter is slightly tilted, it’s still a ‘B’. If the format was analog, those changes would also change the sound/meaning of the word.
