This licence is an almost direct copy of the creative commons Attribution-Sharealike license, but with one key addition:
You are not permitted to process, store, or transmit the licensed material using a digital computer.
This means, among other things:
You are still permitted to take copies of the licensed material, build on them, and share them freely. However, you must do this entirely with analogue technology. You can use a pen and paper to copy a story or poem. You can use a cassette tape recorder to copy a song or a reading. You can use a polaroid camera to copy visual art.
The licensor cannot revoke these freedoms as long as you follow the licence terms.
You do not have to comply with the licence for elements of the material in the public domain or where your use is permitted by an applicable exception or limitation.
No warranties are given. The licence may not give you all of the permissions necessary for your intended use. For example, other rights such as publicity, privacy, or moral rights may limit how you use the material.
We expect that this prohibition on digital processing will likely have some or more of the following effects. These are not part of the licence itself, just some expected possible consequences.
go viral
...or at least not nearly as easily as they could if we were permitted to share them on the internet. Admittedly, if you manage to make a 100% analogue art-piece that goes properly viral, that'd be pretty cool.
If computers aren't allowed to read it, AI's definitely can't. So long as no-one breaks the terms of the licence, there should be absolutely no chance of your art getting regurgitated by a GenAI without your consent.
Of course, if it's your art, you hold the copyright, and you can do what you want. But if all the right you have to the material is the right granted by this licence, then you'll find it very difficult to do any modern publishing with it. Modern books are typeset by computers. Modern music is mastered on computers. How many industrial-scale analogue publishing machines are left in the medium of your choice?
