i.e. You are asking a question about whether using agents to write code is net-positive, and then you go on about not reviewing the code agents produce.
I suspect agents are often net-positive AND one has to review their code. Just like most people's code.
I don't think that's quite it - review is a recurring cost which you pay on every new PR, whereas writing code is a cost you pay once.
If you are continually accumulating technical debt due to an over-enthusiastic junior developer (or agent) churning out a lot of poorly-conceived code, then the recurring costs will sink you in the long run
