I think your concept of ‘what the AI wrote’ is too large. There is zero chance my one line copilot or three line cursor tab completions are going to have an effect on the overall quality of my codebase.
What it is useful for is doing exactly the things I already know need to happen, but don’t want to spend the effort to write out (at least, not having to do it is great).
Since my brain and focus aren’t killed by writing crud, I get to spend that on more useful stuff. If it doesn’t make me more effective, at least it makes my job more enjoyable.
I'm with you. I use Copilot every day in the way you're describing and I love it. The person I was responding to is claiming to code "hands off" and let the AI write the majority of the software.
