Interestingly, they compare number of pull requests as a statistic for productivity. Not that I know of a better metric, but I wonder if this is an accurate metric. It seems similarly misguided as looking at lines of code. If an AI tool makes me more productive, I would probably either spend the time won browsing the internet, or use it to attempt different approaches to solve the problem at hand. In the latter case, I would perhaps make more reliable or more flexible software. Which would also be almost impossible to measure in a scientific investigation. In my experience, the differences in developer productivity are so enormous (depending on existing domain knowledge, motivation, or management approach), that it seems pretty hard to make any scientific claim based on looking at large groups of developers. For now, I prefer the individual success story.
