@danie10 I've put a lot of stuff on archival paper with Optar.

Printed out the source code too.
Maybe my great grandkids will be able to ask their equivalent of ChatGPT to take this and show them what it is. Can't go wrong with physical pictures though.
@daniel yep they would not find (or notice) the source code left stored on one of many hard drives. Printed on paper meant it did mean something to you.
I remember years ago when filing code we had saved it onto a floppy disc and also printed the code onto paper, which was then filed with the disc inside the paper folder.
