Microsoft CEO Satya Nadella revealed on Tuesday that between 20% and 30% of the company’s software code is currently written with the help of artificial intelligence—a figure that could surge to 95% by 2030, according to company projections.

Nadella made the remarks during a fireside chat with Meta CEO Mark Zuckerberg at Meta’s LlamaCon conference, responding to a direct question about how much of Microsoft's code is AI-generated.

He noted that the effectiveness of AI-generated code varies by programming language, citing stronger results in Python, while performance has lagged in more complex languages like C++.

The vision of AI-driven software development is not new at Microsoft. Kevin Scott, the company’s Chief Technology Officer, previously projected that by the end of this decade, 95% of code could be produced using AI tools.

During the same conversation, Zuckerberg admitted he was unsure of the exact percentage of Meta’s code produced by AI.

Meanwhile, Google CEO Sundar Pichai stated during his company’s recent earnings call that over 30% of Google’s code is now being generated by AI, further highlighting the accelerating shift across the tech industry.

However, industry analysts caution that such figures depend heavily on how companies define and measure AI-generated code, and suggest these claims should be viewed with healthy skepticism.
