Well, if you ask Microsoft CEO Satya Nadella, the answer is increasingly the latter. During a recent fireside chat with Meta’s Mark Zuckerberg at LlamaCon, Nadella casually dropped a bomb: around 20% to 30% of the code inside Microsoft’s repositories is now being written by… software. Yes, by AI.
That’s not just autocomplete on steroids — that’s AI stepping in as a co-author on a significant chunk of the build. Nadella pointed out that while the AI’s performance varies by language (stronger in Python, not as hot in C++), the trajectory is clear — code is being co-piloted more than ever.
If that sounds wild, consider this: Microsoft’s own CTO, Kevin Scott, has predicted that by 2030, 95% of all code could be AI-generated. That’s not just tweaking syntax — that’s an overhaul of how software is created, debugged, and shipped.
Zuckerberg, for his part, didn’t offer a number for Meta’s AI-generated code. But let’s be honest — with the speed of LLM development, it’s likely not far behind.
Meanwhile, Google’s Sundar Pichai shared last week that over 30% of code at Google is now AI-generated. The kicker? None of these companies are being crystal clear about what “AI-generated” really means in practice.
But one thing’s for sure: the shift isn’t coming. It’s here. And if your dev team isn’t already riding this wave, you might want to check your horizon — because AI isn’t just helping us code faster. It’s changing the entire blueprint.
