Human - Human and AI - AI mistake and spotting thereof basically cancel each other out, or can be considered no mistake. Human - AI just speaks in favor of AI, and my comment was responding to somebody dismissive of how crushed engineers can feel by AI.
human mistake, AI spots the mistake
Human mistake, human spots mistake
AI mistake, AI spots the mistake.
Everybody is always talking as if they don't make mistakes, but every software engineer does; it used to be that human caught those mistakes and fixed them, but if AI catches those mistakes and fixes them, then that is also a decrease in value of human.
