I use copilot at work all the time and it’s incredibly useful. However, it needs careful supervision to produce good quality. And obviously, you need to understand code and what quality means to be able to guide it, otherwise it’s just the blind guiding the blind.

Personally I think the problem is the culture which doesn’t promote quality, but speed and the wow factor. You don’t get promoted for releasing a bug free product, you get promoted for making yourself noticed among the upper management.
