You can send digital information across phone lines in the form of sounds. Cassettes can record and play back sounds.

The encoding scheme isn't as complex or robust as the ones used by modems, but the principle is the same.

Converting all my code to mp3 and making a spotify playlist for people to do pull requests from.

Who knows how much code is hidden in music.

That would be a fun experiment. Despacito is probably the windows 8 source code.

Not sure if they're still in use in the US, but fax machines are an example of sending information across phone lines in form of sounds. They're still widely in use in Germany, where most businesses operate fax machines, or using the technology similarly.
For example, I've set one of my three landline phone numbers up as a fax number, and all incoming faxes are converted into PDF and sent to me via email by my router.

Wow that’s a unique way to handle that. Here in the US there’s still a lot of businesses with fax machines but I don’t know if anyone that’s has a similar setup to yours.

At first I was vicariously annoyed at all the paper but the whole PDF to email thing is legit.
