Unfortunately we're at the mercy of Goodhart's law and in an interesting twist, AI is really good with things that have an immediate feedback mechanism, eg writing code that doesn't compile or pass tests, but you're trying to grade AI o something that doesn't have an immediate feedback mechanism. AI can slop out a PowerPoint deck in a fraction of the time it used to take a human by hand. The competent human then goes in and unslopifies it, but overall, still time is saved. Unfortunately, that employee is salaried and not hourly, so they can't click out early and even if they were, what's their incentive to clock out early if it means less money in their pocket? Or they can use the hours now free on something else. My gut, as an Internet random who's used AI is that it helps. I don't know how to measure it, just like how do you measure how much better it is to live in a clean house vs a cluttered one? How would you put that in a metric? If you can't put that into a metric, why bother cleaning your house? We clean it anyway, because of a certain je ne sais quoi.
