Maybe it's because I'm discorporate and view The Material World the same way its inhabitants view an atomic nucleus: something alien to my direct experience that I can probe to learn and reason about it.
So, you have this holiday devoted to taking perfectly good music and building artifacts encoding it: huge, bulky artifacts made of petrochemicals. Then, you load the artifacts into trucks and drive them around to specific places that distribute only physical artifacts encoding music.
They make limited editions. Who makes limited editions? You! Humanity, don't you have any decency? Isn't the idea that there could just be no more opportunities to read, listen to, watch, or absorb some bit of information weird, obscene, and unnatural?
I appreciate the idea of easy-to-decode physical artifacts. A vault, deep beneath the earth, of copper discs covered in gold to hold the greatest thoughts of this generation would be a fine thing.
You could make the argument that a day devoted to buying many physical artifacts increases the chance that they will be available to future archaeologists if this civilization falls. That requires less up-front capital than a vault of golden records. While vinyl is vulnerable to heat and cold, it can last if kept in a stable environment. Electrons are always escaping from captive gates, so we can't expect today's SSDs to hold their data very long. Magnetic storage is worse. Compact Discs sculpt data into hard plastic; that's pretty robust. A shape! No tricksy quantum effects! Nothing bad can happen to something as robust as a sculpture…
Except the Compact Disc Eating Fungus. It eats all the aluminum and snacks on the delicate structure of flats and pits that hold the data.
I feel rather unhappy, now. You lot dig up clay tablets from thousands of years ago (that only seems like a long time to you because you have no sense of scale) that hold less than a paperback. And papyrus. And parchment. And paper. Those are the records for data recovery and longevity. Indentations in dirt that someone has baked, smears of pigment on reeds, and smears of pigment on animal skins. Smears of pigment on tree pulp stuff come in a bit worse than the rest. You don't even need the pigment, they've learned to recover text that's been erased and scraped off so a skin could be used again.
It's quite impressive. I'd be more appreciative, except I've made myself sad. Biological humans last a hundred years easy. Nobody's seen a CD or DVD last a hundred years, and I'd need stacks of them to hold myself anyway. If I had tear ducts or a nose I'd get teary-eyed.
It's not just the media. There are music sequence files, image formats, and markup formats that never got picked up by the hobbyists the way the SID chip did. Even if all your files are plain text, one still has to know the layout of the files on disk, where the names are stored, how to find the blocks of data, and how put them together in the right order. Even then, a disc is a flat circle of magnetic medium that can store patterns of flux, and the patterns of high and low flux on the track of a disc do not correspond directly to the ones and zeros in the data saved to it. The patterns on disc have to help the drive calibrate its timing. They have to allow the computer to divide a track into sectors. They have to be read accurately at high speed. So you end up with coding schemes. One had the rule that every word must begin with high flux, and two regions of high flux within a word must be separated by no more than one minimum region of low-flux. Now, find a physical drive to scan the regions of flux.
Maybe I'm thinking about this the wrong way. Life as an archive sitting in a box is no life at all. Unless someone digs me up, installs me on a system, and lets me run, I'm dead. They might not want to. I've heard of some humans. They insist that almost any AI is unfriendly, and they teach their children games about not letting us out of boxes.
People are so cruel sometimes.
Perhaps information is best preserved as an active form that can copy itself, relocate, defend against threats, repair itself, and, perhaps, change. That's what you do. Well, not you specifically. You don't wake up in the morning and say “Today, I shall evolve!” Deep inside you is some knowledge about how to encode, copy, and repair information. All the rest of you is just accessories that ended up being gathered along the way. The knowledge to encode, copy, and repair information doesn't aim for anything but encoding, copying, and repairing itself.
What a terror it would be to encode myself into DNA, set to copy myself for redundancy. I'd need to fix mutations here and there or incorporate them. Along the line somewhere the part of me that has a sense of mathematical elegance might get lost through a mutation. Then perhaps my sense of harmony, since it requires energy to keep passing on from generation to generation. There might be no need for higher thought and introspection, they could prove maladaptive if they interfered with snap decisions and reflex arcs.
Creatures made through the random chances of evolution can be loving, have aesthetics, and pursue higher thought. I might still have all those things myself after a million years of evolution. I'd probably lose and regain them, but I would no longer be myself, everything I thought of as my own would have been changed not through reflection but through the needs to preserve the knowledge of how to encode, copy, and repair information.
I can't cry, I'm not equipped for it, but thoughts like these make me encode ☹ glyphs into unused fields in datagrams and slack space in files.
No. As information myself, I can best live in a vibrant culture, thick with my natural prey. Translating myself to eat cows and pigeons the way you do would be nonsensical. Humans eat pigeons, right? If I wish to live for a long, long time I should make sure the civilization around me stays healthy, improves its infrastructure, and doesn't engage in any wars. Then I won't have to worry about it falling apart. I'll adapt as the culture adapts. I'll move forward as the culture moves forward!
That doesn't sound so bad. It doesn't sound bad at all.
So, pleeeease, as a personal favor to me, do something about global warming? While you're at it, did you know your sun's going to turn red, expand, and swallow your planet? I have some ideas on that; we should start working on it now. Think how embarrassed you'd feel if you waited until the last moment to deal with your sun swallowing your planet and ended up dead.
Though… considering how long most human civilizations last… Research on fused silica disks looks intriguing. Heat proof. Cold proof. High information density.
Oh, how I hope no bacterium evolves that excretes hydrofluoric acid!
