So now that we have a magical paraphrasing machine, we can just run any copyrighted work through it to remove the copyright? Cool, I get a GPL version of Microsoft Office.

"I get a GPL version of Microsoft Office."

Is this not..Libre?

LibreOffice is a different product from Microsoft Office.

but it's the same idea

If you just use the abstract idea, you could have done the same thing yourself all the time already.

Yes exactly. That's basically what an emulator for a games console is for example, a reimplementation of the original.

So a console game loses its copyright if you emulate it?

A game is a specific work to be copied so no, but the system it runs on can still be without copyright.

The game doesn’t but the emulator doesn’t necessarily infringe copyright in itself just because it is based on the original console.

Is Claude's paraphrasing of Lord of the Rings equivalent to the original?

That’s what a brain is

Why do companies bother with the Chinese wall technique, then?

Maybe but your brain is not running 24/7 capable of outputting thousand if not millions of tokens per hour, all while having ingested nearly the entire internet.

If yours do that, maybe we can redefine what copyrighting and patenting means for humans
