I'm sure I am not the first to have remarked on this, but I'm finding that coding with copilot really rewards a good coding style in general. Like it has a much easier time filling in details thoroughly and correctly if I write a module "the most obvious way", and stick to non-clever, obvious 1-task functions with clear names, and equip each with a thorough comment explaining what it's doing and why. Which is the kind of work my better-self _wants_ to be doing all the time. The thing is just nudging me fairly hard to listen to that better self, because if I get too clever, terse or opaque in my work it'll stop helping.
@graydon I've heard some writers say similar things about ChatGPT - that it can be a useful partner if you pre-outline your thoughts and use ChatGPT to flesh that out, or to act as a very smart thesaurus, or very junior (must-be-checked) research-assistant. You have to be deliberate and specific, which *can* encourage good habits. But obviously also can go way off the rails.
