Big Tech embraces AI coding, hitting 30% of software

With Satya Nadella’s announcement overnight that Microsoft uses AI to code around 30% of their software, AI coding has come of age. Other Big Tech companies have also reported similar numbers lately.

— I’d say maybe 20%, 30% of the code that is inside of our repos today and some of our projects are probably all written by software, said Microsoft CEO Satya Nadella during a conversation at LlamaCon, Meta’s AI developer conference, according to CNBC

Microsoft says they have made progress with Python, and less with C++ projects, but he is still pointing that some projects could be entirely written by AI.

The goal is 95%
Their chief technology officer, Kevin Scott, said earlier in April that the goal was for 90% of code to be AI-generated within the decade, writes Business Insider.

On Google owner Alphabets recent earnings call, CEO Sundar Pichai put the percentage of AI written code at 30%, according to Analytics India Mag, reaching the same level as Microsoft, adding that Gemini 2.5 Pro opens up «new possibilities» for math and coding.

50% ai code from meta this year
Not to be upstaged, Mark Zuckerberg, of Meta, in the same chat said he has no idea how much of his code is currently written by AI, but added a clear target for 2026:

— Our bet is sort of that in the next year probably … maybe half the development is going to be done by AI, as opposed to people, and then that will just kind of increase from there, said Zuckerberg, according to Mashable

Engineers’ roles will change
Zuckerberg later added that the future of coding work is going to be more like overseeing a team of AI agents rather than doing all the coding themselves, adding that:

— Every engineer is effectively gonna end up being more of like a tech lead, and they will all have »their own little army of agents that they work with.”

At the same time, the founder of AI coding platform Cursor.ai, took to Twitter on occasion of their quarterly report with this tweet:

Cursor writes almost 1 billion lines of accepted code a day.

To put it in perspective, the entire world produces just a few billion lines a day.

Indicating that the fine art of coding is rapidly being taken over by AI coding tools.

Layoff plaguing the industry
Microsoft, Meta and Alphabet retain tens, if not hundreds of thousands of software engineers, and have been laying off a lot of them lately.

Intel recently confirmed it was laying off 20,000 people, Meta has announced it will cut its workforce by 5%, and Microsoft says it’s doing the same.

50,000 people from 100 tech companies have been laid off so far this year, according to Techspot.
