What surprises me is that this obvious inefficiency isn't competed out of the market. Ie this is clearly such a suboptimal use of time and yet lots of companies do it and don't get competed out by other ones that don't do this
Short term gets faster more competitive results than long term.
I think the issue is everyone's stuck in the same boat - the alternative to using AI and spending time reviewing is just writing it yourself, which takes even longer. so even if it's not a net win, it's still better than nothing. plus a lot of companies aren't actually measuring the review overhead properly - they see 'AI wrote 500 lines in 2 minutes' and call it a productivity win without tracking the 3 hours spent debugging it later. the inefficiency doesn't get competed out because everyone has the same constraints and most aren't measuring it honestly
