This is going to end either with seniors rubber-stamping absolutely everything without even reading or with seniors blocking most of the slop for no overall productivity gain
Or if review is actually done I think there will be productivity loss. Juniors with help of AI can generate more code than seniors have time to review in full working day. So they won't have time left for any other work...
No, it’s Amazon. If a senior blocks the slop they will be told they are not disagreeing and committing enough. If bugs get through they will be told they didn’t dive deep enough. It’s classic Amazon blame game. Someone gets left holding the bag for impossible asks (hint: it’s never the person doing the ask), and then gets piped and fired.
