70 years ago Miles Davis vibrates some air with his horn, which is translated into electricity by a microphone, which is translated through magnetic tape and eventually back into electricity and then back into vibrations on a disk. 70 years later I can take that disk and turn its vibrations back into electricity that moves the air on my living room. No encoding, no decoding, just air and electricity that my ancestors will be able to replay until the end of time.
That's as close to magic as anything humanity has ever come up with in my opinion.
Personally I see far more magic in digital electronics. Storing vibrations physically is neat and clever, but none of that looks particularly magic to me. Just a straightforward, logical solution to a problem. More elegant simplicity than magic really.
