TL;DR: Microsoft CEO Satya Nadella revealed that AI now writes up to 30% of the company’s new code, highlighting a significant shift toward AI-driven software development. Meta’s CEO predicts AI will handle half of their coding soon, signaling a major transformation in how tech giants develop and maintain software.

We haven't stopped hearing about AI for a couple of years now, but recently Microsoft CEO Satya Nadella admitted that as much as 30% of the company's new code is written by AI.

Microsoft CEO Satya Nadella revealed the news during the recent LlamaCon, which is Meta's conference focusing on generative AI tools, where when sitting across from Facebook founder and CEO Mark Zuckerberg when he said: "code reviews are very high. In fact the agents we have for reviewing code, that usage has increased, and so I would say maybe 20, 30 percent of the code that is inside of our repos today and in some of our projects are probably all written by software".

Nadella also asked Zuckerberg how much of Meta's code was being written by AI, to which Zuckerberg said he didn't know the exact figure off the top of his head, but noted that Meta is building an AI model that can in-turn build future versions of Meta's in-house Llama family of AI models.

Zuckerberg said: "Our bet is sort of that in the next year probably... maybe half the development is going to be done by AI, as opposed to people, and then that will just kind of increase from there".

Considering all of the issues that Microsoft has been facing with Windows over the years, and as a long-time PC enthusiast of over 30 years now, it's beginning to make sense as to why the issues haven't been going away. You'd think that with all of the power of AI that the code for Windows would be perfect, Windows Update would be perfect, and we wouldn't have a hitch... after all we've got artificial intelligence (which is being heralded as the best thing ever) looking after your PC.

It would be cool if we had an AI that would take care of issues, where a situation like a BSOD is about to occur and the AI sees it happening in real-time and fixes it before you even notice. Let's say you're switching from working to playing games? The AI knows this an intelligently shuts down background services and apps to free up more resources for gaming... that would be cool. But it seems AI will be taking over a considerable amount of developer jobs in the future at Microsoft.
