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?
Because such code is dumb, tedious and joyless. I have to bite my lip sometimes to convince myself writing them is not a waste of time, because people demand it, but I hate it to my core.
Copilot is that unfortunate boy that has to do all that manual work. It is the ultimate code boilerplate mixer.
It is not going to write all code for you, if you goal is to have it THINK for your then you are due to disappointment. But it would be able to help you be a more efficient and slightly happier programmer.
