The fundamental flaw with pitching CoPilot as a massive productivity boost is that its goal is to make it faster and easier to generate code.

As a programmer, you don't want to generate code. You want to solve problems; the less code involved the better. I don't want tools that will generate repetitive code, I want less repetition.
