Don't get me wrong, the folks behind Copilot are clearly, without any doubt smart, creative, and capable. But then... None of these issues (reproducing licensed code ad verbatim, non-compiling code, getting semantics wrong, and now this) are 0.01% edge cases that take specialized knowledge to see or trigger. I remember some of them being called days ago in the initial HN thread by people who haven't had beta access.
I really wonder how this announcement/rollout looked like on the management side of things. Because a) these shortcomings must have been known beforehand and b) backlash from people who feel threatened for their jobs/"stolen" of their open source work was (I guess) foreseeable? I've already read calls to abandon GitHub for competitors; this can hardly have been an acceptable outcome here.
Nevertheless, Copilot is still one of the most innovative and interesting products I've seen in a while.
