US Copyright Office found AI companies breach copyright. Its boss was fired

The released draft report seems merely to be a litany of copyright holder complaints repeated verbatim, with little depth of reasoning to support the conclusions it makes.

The required reasoning is not very deep though: If an AI reads 100 scientific papers and churns out a new one, it is plagiarism.

If a savant has perfect recall, remembers text perfectly and rearranges that text to create a marginally new text, he'd be sued for breach of copyright.

Only large corporations get away with it.

Is reading and memorizing a copyrighted text a breach of copyright? I.e. is creating a copy of the text in your mind a breach of copyright or fair fair use? Is it a breach of copyright if a digital “mind” similarly memorizes copyrighted text? Or is it only a breach of copyright to output and publish that memorized text?

What about loosely memorizing the gist of a copyrighted text. Is that a breach or fair use? What if a machine does something similar?

This falls under a rather murky area of the law that is not well defined.
