Magazines would print out their source code and you could scan it in. Of course I had no money to buy such an expensive machine so was relegated to mind numbing typing and the inevitable typos that came with it.

#4Has anyone actually used this? I'm intrigued by the idea and wonder if this is a viable backup option; and if so, are there more modern, maintained, and cross-platform open source solutions that do this?

#5this has some pretty powerful applications for example for politics or mass dissemination of paper based digital files for the public to quickly consume.
Imagine, if students could start posting free textbook pdf files just by handing out a piece of paper which you could scan, or maybe with a phone one day, and instantly receive the file.
Why not QR code? QR code needs connectivity while this solution would just require you to get your hands on the paper.

#6So I'd like this on medium that's a bit more permanent than paper, but with similar information density per kg, and similar re-creatability without having any of the original tools available. I'd like to store data for say 100 thousand years.

Tyvek, perhaps? I'm not sure how long-term it would stick around, but it wouldn't decay as fast as paper in an unprotected environment.

Archiving data to 35mm motion picture film has been done, including putting the source code to the decoding software on the leader of the film.

You beat me to it. Tyvek would be an excellent candidate for its amazing durability and that it behaves much like paper (at least in terms of texture).

An IBM researcher did this with a Tyvek-like material in the 90s, a polyester made by DuPond if I remember correctly. Just tried to google a reference but no luck.
