the person using co-pilot on all their hobby projects described it as working best as an advanced auto-complete, so I guess you should ask them that.

I figure advanced auto-complete should not produce big blocks of code that are more likely to have logical errors in them, since the grandfather comment here suggested that problems show up when you generate larger blocks of code.

this is consistent with the feedback from many of the users we have talked to as well (transparently I am with Tabnine). Long blocks of code are difficult to digest while short quick ones can be very quick AND easy to validate the logic.
