Prime Highlights:
- Microsoft CEO Satya Nadella announced AI produces as much as 30% of the company’s code.
- Python experiences more AI usage compared to complex languages such as C++.
Key Facts:
- Microsoft predicts AI to produce 95% of code in 2030, according to CTO Kevin Scott.
- Google asserts more than 30% of its code is AI-generated.
- Meta has not announced a specific percentage of code generated by AI.
Key Background :
During Meta’s inaugural LlamaCon developer conference in April 2025, Microsoft CEO Satya Nadella made a telling remark: between 20% and 30% of all code in Microsoft is now being authored by artificial intelligence. This dramatic development underscores how deeply AI has penetrated contemporary software engineering.
Nadella described that the generation of AI code is not consistent in terms of programming languages. For example, programming languages such as Python — which are famous for ease of use and flexibility — are experiencing greater percentages of code generated with AI. More technical, low-level languages such as C++ are less impacted due to the complex syntax and hardware-level interactions required. This observation serves to show that although AI tools are developing incredibly fast, they are still constrained in working with highly technical or specialized coding environments.
Microsoft isn’t alone in this technological shift. Google has also disclosed that more than 30% of its code is now written by AI, although measurement standards for what qualifies as “AI-generated” differ between organizations. This inconsistency points to a larger industry need for clear frameworks or definitions when tracking AI’s role in development.
Later in the same session at LlamaCon, Nadella inquired of Meta CEO Mark Zuckerberg how much of Meta’s code is AI-generated. Zuckerberg confessed that he didn’t know the percentage exactly, leaving the inference that Meta either does not keep the figure closely or hasn’t seen fit to advertise it.
Microsoft CTO Kevin Scott has set out an ambitious vision for the future, foreseeing that by 2030, up to 95% of all software code will be written by AI. This estimate highlights the increasing dependence on AI to improve productivity, minimize routine workload, and speed up the software development process.
But with more AI in the mix comes more responsibility. Developers and technology leaders need to be actively concerned about quality control, security loopholes, and ethical practices. While AI starts programming much of the code driving apps, services, and infrastructure, human judgment will be crucial to check logic, safeguard users, and maintain accountability.
In brief, Microsoft’s announcement represents a turning point in the history of coding—when the partnership between human engineers and AI systems is transforming the entire ecosystem of software development.
