Correct, but that has and probably always will be the case.

You spend the time on what is needed for you to move ahead - if code review is now the most time consuming part, that is where you will spend your time. If ever that is no longer a problem, defining requirements will maybe be the next bottleneck and where you spend your time, and so forth.

Of course it would be great to get rid of the review bottleneck as well, but I at least don't have an answer to that - I don't think the current generation of LLMs are good enough to allow us bypassing that step.
