Naively, as someone who just heard of this - that sounds worse than useless. If you can't trust its output and have to verify every line it produces and that the combination of those lines does what you wanted, surely it's quicker just to write the code yourself?
Just today I needed to quickly load a file into a string in golang. I haven't done that in a while, so I had to go look up what package and function to use for that. I'd love a tool that would immediately suggest a line saying `ioutil.ReadFile()` after defining the function. I would never accept a full-function suggestion from Copilot, similarily to how I never copy and paste code verbatim from StackOverflow. Using it as hints for what you might want to use next seems like a nice productivity boost.
