Plagiarism can only be spotted by people who wrote the original work?

copilot's won't suggest anything worth calling plagiarism, just mundane plumbing and maybe textbook algorithm implementations. have you seen it generate anything more glorified than StackOverflow-esque code snippets?

They had to blacklist Q_sort because they couldn't stop copilot from copying the complete function with comments (not just the algorithm) from the quake source, however it did not autocomplete the correct license for it.

It's dicey according to the GPL FAQ [1]. It goes against what GPL authors want: their work being used in proprietary projects.

This could have been prevented very simply: GitHub avoiding training Copilot on GPL code.

What they can still do is offer a new model excluding GPL code for people who care about it.

They would also have to exclude virtually all code that isn't public domain, too. MIT and Apache-2.0 and BSD all require that the copyright notice and license text is preserved in downstream use.

It may work if you design/architect houses for clients.
