> copyright does not only cover copying and pasting; it covers derivative works. github copilot was trained on open source code and the sum total of everything it knows was drawn from that code. there is no possible interpretation of "derivative" that does not include this
Copyright law is very complicated (remember Google vs Oracle?) and involves a lot of balancing different factors [0]. Simply saying that something is a "derivative work" doesn't establish that it's copyright infringement. An important defense against infringement claims is arguing that the work is "transformative." Obviously "transformative" is a subjective term, but one example is the Supreme Court determining that Google copying Java's API's to a different platform is transformative [1]. There are a lot of other really interesting examples out there [2] involving things like if parodies are fair use (yes) or if satires are fair use (not necessarily). But one way or another, it's hard for me to believe that taking static code and using it to build a code-generating AI wouldn't meet that standard.
As I said, though, copyright law is really complicated, and I'm certainly not a lawyer. I'm sure someone out there could make an argument that Copilot is copyright infringement, but this thread isn't that argument.

Edit: Note that the other comments saying "I'm just going to wrap an entire operating system in 'AI' to do an end run around copyright" are proposing to do something that wouldn't be transformative and therefore probably wouldn't be fair use. Copyright law has a lot of shades of grey and balancing of factors that make it a lot less "hackable" than those of us who live in the world of code might imagine.
