In my experience, code validation (unit testing, code review, manual testing, etc.) was more of a bottleneck than producing code for the most part. This means that faster code generation wouldn't produce significant gains in throughput unless the code validation speeds up too. In my workplace, I've seen evidence that the people showing the biggest productivity gains from AI coding are now shipping enormous commits that are barely getting any validation. Given the Zeitgeist, others are for some reason more lenient towards that than they normally would be (or should be).
