Some sections that caught my eye:
"As an example, the idea of lions loosely doing Hamlet is not copyrightable, but the implementation of that idea in the form of the film “The Lion King” is. In legal terms, this separation of what is and is not covered by copyright is generally referred to as the “idea-expression dichotomy”."
"The copyrightability of photographs, for example, was the subject of considerable debate at the time when cameras were new inventions, as can be seen in a US Supreme Court case from 1884 (“Burrow-Giles”). Here, it was argued that photographs were the products of machines and therefore lacked the requisite human authorship to be copyrightable."
" With these issues in mind, the recently published Recommendations When Using LLM-Backed Generative AI Systems for FOSS Contributions by the SFC outlines some of the legal difficulties for copyright and licensing that generative systems have created for software developers who wish to write, maintain, or contribute to Free Software projects."
