Thanks for the comment. As the author (but I didn't submit it to HN) I see in hindsight that the title should have been a little more informative rather than feeling so click-bait-ey.

My goal was not to imply that we're not shipping faster than we were prior to AI, as I think that's beyond debate at this point. What we investigated is why we're not shipping faster than we are today. If (high quality) code is being written at five times the rate it was before and we're shipping "only" twice as fast, then what's the reason for the difference? The talk shares results from studies that help improve our understanding of why.
