In a statement that raised both eyebrows and questions across the tech world, Microsoft CEO Satya Nadella recently revealed that up to 30% of the company’s code is now written by AI.
Yep, you heard that correctly – nearly a third of the code powering one of the biggest tech giants on the planet is not being typed out by humans, but generated by machines. That’s just about as impressive as it is terrifying, so is it a sign of progress or a red flag with a glowing LED?
AI-assisted coding tools like GitHub Copilot (which Microsoft owns), Amazon’s CodeWhisperer and Google’s Codey are already reshaping how developers write, test and deploy software. These tools are trained on massive datasets of publicly available code and documentation and can autocomplete lines, generate snippets or even spit out entire functions based on a few prompts.
Indeed, in Microsoft’s case, Copilot is now helping thousands of developers across the company, sometimes writing lines of code before they’ve even had their second coffee. In a way, it’s almost democratising the world of code-writing, breaking down barriers of entry.
But, is that a good thing? While 30% is a hefty chunk, the more important question is how good is that 30%?
When AI Gets It Right
There’s no arguing the fact that when AI is good, it’s good. It can absolutely shine when it comes to boilerplate code – the repetitive, mind-numbing stuff that most developers dread. Think writing test scaffolding, generating configuration files or churning out common algorithms. It’s like having a super-speedy intern who never sleeps and doesn’t need coffee breaks.
There’s also a serious productivity gain. According to Microsoft, developers using Copilot complete tasks up to 55% faster, because it frees them up to focus on more complex logic, architecture decisions or actually thinking creatively, so to speak.
And as for newer programmers, AI can also act as a learning tool, offering suggestions that help them understand structure, syntax and style without constantly scouring Stack Overflow.
But, What Happens When AI Gets It Wrong?
Unfortunately, AI-generated code isn’t always a win. At best, it might be clunky. At worst, it could be buggy, insecure or completely inappropriate for the task. Because AI models are trained on vast quantities of public code – including flawed, outdated, or vulnerable examples – their output can inherit those same flaws, kind of like how bias that exists within data sets is simply perpetuated whenever the daa sets are used.
Security experts have warned that blindly trusting AI suggestions could introduce vulnerabilities into software. Remember, AI doesn’t actually understand the code it writes – it’s simply predicting patterns based on probability. That’s fine when you’re auto-completing a for-loop, but not so great when you’re writing authentication logic or data-handling functions.
Then there’s the issue of accountability. If a bug causes a catastrophic failure and it was written by an AI, who takes the blame? The developer who accepted the suggestion? The company that integrated the tool? The AI model itself, twiddling its virtual thumbs in the cloud? It may sound like a small issue, but this is actually a very serious aspect of the issue that needs to be considered.

Creativity Vs. Completion
There’s a subtle difference between writing code and merely completing code – it’s the difference between doing something properly and simply getting it done.
Much of what Copilot and similar tools do is the latter – they autocomplete based on context. And that’s helpful in many situations, sure, but it’s a far cry from architecting a system from scratch. AI still lacks the nuanced reasoning, domain knowledge and problem-solving instincts that experienced developers bring to the table.
In other words: AI can be brilliant at finishing your sentences, but don’t expect it to write your novel – at least, not yet.
So, Should AI Be Writing 30% of Code?
The fact that it can is one thing, but should it?
Here’s the cheeky answer: it depends on which 30%. If AI is writing the repetitive, safe, low-stakes stuff, go ahead – hand it over. Developers can get more done, learn from suggestions and spend more time doing what humans do best – thinking critically, collaborating and solving big problems. It’s pretty much the same way we deal with the use of AI in other things like admin and even writing.
But, if we’re talking about AI writing complex, security-sensitive or mission-critical systems, you might want to pump the brakes. Tools like Copilot are best seen as collaborators, not replacements. They can assist, inspire and even surprise, but ultimately, they still need adult supervision.
Microsoft’s 30% claim is a bold benchmark. It tells us AI is no longer just dabbling in development, it’s got its own seat at the table. But whether it should stay for dessert depends entirely on how well we use it and what we ask it to do.
