LWN has a little article on github copilot https://lwn.net/SubscriberLink/862769/9cbeaabb61b9d47c/

Also links to https://gist.github.com/0xabad1dea/be18e11beb2e12433d93475d72016902 which is pretty interesting

I like this quote from the github gist:
> The inevitable conclusion is that Copilot can and will write security vulnerabilities on a regular basis

😂
