I wasn't joking, it's a bottleneck sometimes, that's it. It's a bottleneck like comfort and any good tool is a bottleneck, like a slow computer is a bottleneck. It's silly to suggest that your ability to rapidly use a fundamental tool is never a bottleneck, no matter what other bits need to come into play during the course of your day.

My ability to review and understand intent behind code isn't a primarily bottleneck to me actually efficiently reviewing code when it's requested of me, the primary bottleneck is being notified at the right time that I have a waiting request to review code.

If compilers were never a bottleneck, why would we ever try to make them faster? If build tools were never a bottleneck, why would we ever optimize those? These are all just some of the things that can stand between the identification of a problem and producing a solution for it.
