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?
It never prompted me with any code that was useful. It only ever slowed me down and caused me frustration. It’s nothing like Intellisense. It’s just trash.
