I would then have to wonder if all the time saved in the first place at all. I have heard anecdotes of verifying AI output to be more time-consuming and generally even more painful/stressful than doing the whole work yourself perhaps.

As an employee, I would prefer to not be stressed and as an employer, I would prefer to not additionally stress my employee on all times so that I can have them use the stress for the works which truly matter the most (which is a limited resource as an employee shouldn't be burnt out or shouldn't be given unlimited stress)

Also its probably the ethical thing to do but even rational logic dictates so in my honest opinion (not sure how much of it works exactly on documentation stuff though*)
