CEO of Microsoft, MSFT, Satya Nadella, has said as much as 30% of Microsoft code is written by AI

Microsoft CEO Satya Nadella revealed Tuesday that up to 30% of the company's code is now being generated by artificial intelligence tools.

“Probably 20% to 30% of the code in some of our repositories and projects is written by software,” Nadella said during a live conversation with Meta CEO Mark Zuckerberg at Meta’s first LlamaCon AI developer event in Menlo Park, California. He noted that the percentage is steadily increasing.

When asked about AI's role at Meta, Zuckerberg didn't offer a specific number but said the company is actively developing an AI system capable of creating future versions of its Llama language models.

“Our expectation is that within the next year, possibly around half of all development could be handled by AI, and that share will only grow,” Zuckerberg said.

Both Microsoft and Meta employ tens of thousands of software engineers, but they are now among the growing number of companies publicly acknowledging that AI is beginning to replace certain tasks traditionally handled by human developers.

Since the launch of ChatGPT by OpenAI in late 2022, businesses have increasingly turned to AI for tasks ranging from customer service and sales content creation to code generation.

Other major tech leaders have shared similar shifts: Google CEO Sundar Pichai said last October that over 25% of new code at the company is AI-generated. Earlier this month, Shopify CEO Tobi Lütke informed employees they would need to prove AI couldn’t perform a task before additional hires would be considered. Duolingo CEO Luis von Ahn recently announced the company would begin replacing human contractors with AI solutions.

Meanwhile, OpenAI has reportedly been in talks to acquire Windsurf, a startup developing “vibe coding” software that can generate entire programs based on a few simple prompts—underscoring the growing vision of machines becoming integral partners in software development.
