It is in the video “Welcome to LlamaCon 2025 - Closing Session!” posted in full on YouTube, around minute 44. Zuck asks: “in terms of the coding, and how it improves that, do you have a sense of how much of the code, like what percent of the code that’s being written in Microsoft at this point is written by AI as opposed to by engineers?” Nadella: “yeah so there’s two sort of thing we’re tracking, one is the accept rate itself, that’s around 30-40, it’s going up monotonically, [talks for a bit about the fact that it works well with Python, less so for C++, from context he’s talking about code completions here, now back to…] the place where the agentic code still, it’s ver-it’s sort of nascent—for new greenfield it’s very very high—but as I said nothing is greenfield in many cases and so therefore I’d say maybe at this point the PR—oh by, the way the code reviews are very high, and so, the agents we have for reviewing code [makes a happy expression], so that usage has increased—and so I’ll say, [this is around 45:00] maybe 20-30 percent of the code that is inside of our repos and some of our projects are probably all, uh, written by software. […] I dunno. In conclusion having listened to it a couple times and done my best at transcribing it fairly close to what he actually said, I’m still confused as to what he meant. I was going to try and make some point with this, but I lost track of it while writing out the quote. At least folks have the full thing to argue about here, more or less! |
