As I said here and elsewhere: If management is concerned code review is a bottleneck, let management be aware that the process has to change. Either the human is not as thorough, or he uses some combination of his brain + LLM to conduct the review.
It's a basic fact: They have a machine that produces a lot of code, but don't have a machine to review that code. The bottleneck is obvious. I'd love to build planes for $1 too, but physics applies.
