I completely agree, as a fellow senior coder. It allows me to move significantly faster through my tasks and makes me much more productive.
It also makes coding a lot less painful because I'm not making typos or weird errors (since so much code autocompletes) that I spend less time debugging too.
Conceptually it was a really simple bug (I was returning a bounding box and it returned (min, min) instead of (min, max)). So, I mean, the amount that AI broke it was pretty minor and it was mostly my fault for not seeing it when I generated it. But you know, if it's messing stuff up when it's generating 4 lines of code I'm not really going to trust it with an entire file, or even an entire function.
I dunno, I just had Copilot sneak in a typo today that took about ten minutes of debugging to find. I certainly could have made a similar typo myself if copilot hadn't done it for me, but, all the same copilot probably saved me a minute worth of typing today but cost me 10 minutes of debugging.
