Copilot frequently produces results that need to be fixed. Compilers don’t do that. Anyone who uses copilot to generate code without understanding how that code works is a shit developer. The same is true of anyone who copies from stack overflow/etc without understanding what they’re copying.
I was trying to make a point without starting a flamewar that was beside the point. Personally I’d never choose a dynamically typed language for a production system. That being said, Python and Ruby complain if you try to add an array, dict/hashmap, string, or number to another (of a different type) so they’re certainly more sane than JavaScript.
I think the author's primary point is, "Merging changes sucks, don't make your users do that," with a corollary: if your program loads configuration from a directory that is only populated by the user, there's nothing to merge and thus never any merge conflicts. Case in point: /etc/polkit-1/rules.d
. I can add whatever rules files I want in there and they're never going to conflict when I update. If PolKit makes breaking changes to the format, it will log errors somewhere and I can look at those errors, look at my rules, and figure out how to fix them. That's a hell of a lot easier than merging conflicting changes to code/configuration.
Additionally, switch performs extra sanity checks that checkout doesn't, for example switch would abort operation if it would lead to loss of local changes.
What checks? Under what situation does checkout lead to loss of changes? If I make changes and attempt to checkout a ref that would overwrite them, I get the following error:
error: Your local changes to the following files would be overwritten by checkout:
some/file
Please commit your changes or stash them before you switch branches.
Aborting
To my knowledge it's not possible to overwrite changes when switching branches/refs (git checkout <ref>
without any other arguments or flags) so I guess what the author really means is, "If you use checkout incorrectly you can overwrite local changes." As far as I can recall I've never accidentally git checkout <ref> <some/file>
so I don't see a reason to retrain my muscle memory. I do use git restore
since it's behavior is a lot more obvious than checkout/reset though sometimes I still use git checkout <ref> -- <some/file>
because muscle memory.
I won't say copilot is completely useless for code. I will say that it's near useless for me. The kind of code that it's good at writing is the kind of code that I can write in my sleep. When I write a for-loop to iterate over an array and print it out (for example), it takes near zero brain power. I'm on autopilot, like driving to work. On the other hand, when I was trialing copilot I'd have to check each suggestion it made to verify that it wasn't giving me garbage. Verifying copilot's suggestions takes a lot more brain power than just writing it myself. And the difference in time is minimal. It doesn't take me much longer to write it myself than it does to validate copilot's work.
