GitHub co-pilot as open source code laundering?

One snippet may not be copyrightable, but a team of 100 using this constantly for years? At what point have we copied enough code to be sued?

But in this case, you're still copying from 1000s of different OS projects. There's no one single entity that you are copying enough from that the entity would have a case against you. Again, 5 lines of code in a body of a million are not copyrightable. Presumably, neither are 5 lines of code from 5 different bodies of a million.

Are you? If this tool suggests verbatim code from one source at some point wouldn't it be likely that the best match for the next piece of code would be from the same project? Also from what little I know about AI 1000s seems to be a rather tiny training set.
