From the short-time I've used it, it's clear that Github Co-Pilot is just a fancy Google Search in that it helps with remembering syntax and keywords which is already helpful, in speeding-up the boiler-plate writing and so is really a big help.
No one is supposed to mindlessly follow the Github Co-Pilot suggestions and of course if judged by that metric it won't help with code quality; but if used properly to quickly type-out boiler-plate code then that is when it becomes useful.
How many times does anyone want to write a for-loop or remember the syntax of how to declare something, especially when juggling multiple programming languages? It's these kinds of things that Co-pilot is good at.
We need to do it as individuals, as groups.
We need to alert employers of the potential legal consequences.
We need to educate developers to not use it.
