I completely agree with you. But I am afraid we are losing the battle.

I am seeing people repeatedly sending out gigantic PRs full of slop, code with mistakes that they would never have made if they were hand coding it. And they don't care. It's sometimes surprising if not horrifying to find that the colleagues you have worked with for years don't care about quality at all -- almost despising spending time reviewing their own code. Yet they have the audacity to send out code reviews.
