Zuckerberg Says AI Will Write Half of Meta's Code; Nadella Admits Microsoft Already Using Robots for 30% of It

At the first-ever LlamaCon AI developer conference, an impassioned exchange between Meta CEO Mark Zuckerberg and Microsoft CEO Satya Nadella revealed the surging role of AI in coding, and the stats are astonishing.

In the final keynote, Zuckerberg asked a question that echoed throughout the tech industry: How much of Microsoft's code is now written by AI? Nadella replied that 20 to 30 percent of Microsoft's repositories are now written by AI, with some projects being written entirely by machine learning models.

AI-Powered Coding: From Tool to Teammate

Zuckerberg Says AI Will Write Half of Meta's Code; Nadella

Zuckerberg's own projection for Meta's future was even more optimistic. While he conceded he didn't have precise numbers at his fingertips, the CEO forecast at the LlamaCon conference that "maybe half the development is going to be done by AI" in a year.

The tech billionaire implied this percentage would only increase, foreshadowing a quickly approaching future in which AI-created code overwhelms development cycles.

While AI coding software such as GitHub Copilot, Meta's Code Llama, and Google's internal models have been promoted as productivity enhancers, the executives' comments reflect a move from augmentation to automation. As Nadella put it, some Microsoft projects are now "probably all written by AI software."

This isn't a dream of the future—it's already here for leading tech companies. According to Engadget, Google CEO Sundar Pichai recently disclosed that 25% of Google's code is already AI-written.

For the moment, human developers still check and maintain the code, but AI is quickly becoming the frontline coder.

The Rise of Agentic AI Systems

As the keynote wore on, Zuckerberg and Satya Nadella moved toward agentic systems, AI that generates not just code but acts on it, does tasks, and runs workflows.

Zuckerberg foresaw a future wherein "every engineer is basically gonna end up being more of like a tech lead," with each leading "an army of AI agents."

This ambitious vision entails engineers moving away from manual coding to managing autonomous software engineers—a significant paradigm shift in how we create and deploy technology.

Quantifying Progress Beyond Code

According to Mashable, Nadella underscored the necessity of new metrics to measure AI's success, not merely by productivity, but by impact in the real world. He encouraged the industry to envision AI increasing the GDP of emerging economies by 10%, showing a global, inclusive vision for AI's potential.

As much as Meta and Microsoft are rivals in the AI arms race, with Microsoft's strong connection to OpenAI and Meta's effort towards open-source models such as Llama, the debate during LlamaCon exposed a mutual realization: AI is revolutionizing the tech industry from scratch.

Nadella's attendance at a Meta-hosted event was telling. It meant that cooperation and conversation are essential, even between competitors, as the world enters a time when AI can code like a human coder.
