This is exactly it. I’ve worked with 2 different teams in this new era. One has all strong engineers and good review and testing standards. The other has 20% bad engineers that should have been fired years ago and’s weaker testing culture. The result is the strong team is delivering higher quantity software faster than ever, and the other team is going fast with much worse results. The quality is very bad, and the good engineers still there are quitting.

The good engineers spend their whole days just trying to keep the ship afloat and minimizing the harm from the bad engineers. They hate it and are burning out fast.
