In terms of difficulty, writing code is maybe on average a two out of ten.
On average, maintaining code you wrote recently is probably a three out of ten in terms of difficulty, and maintaining code somebody else wrote or code from a long time ago probably rises to around a five out of ten.
Debugging misbehaving code is probably a seven out of ten or higher.
GitHub Copilot is optimising the part of the process that was already the easiest, and makes the other parts harder because it moves you from the “I wrote this” path to the “somebody else wrote this” path.
Even during the initial write, it changes the writing process from programming (which is easy) to understanding somebody else’s code to ensure that it’s right before accepting the suggestion (which is much less easy). I just don’t understand how this is a net time/energy savings?
Like a pulling values from a config dict and initializing a bunch of methods from the class? Or setting up a testcase similar to the one you already have, but with different values? Or cleaning values from a form? It's not a bulk edit. But it's also not thoughtful code-writing. It's monotonous and mundane. And lots of people do a lot of this on a daily basis.
Copilot makes this a cinch.
