OpenAI president says AI now writes up to 80% of code, marking a major shift in how software is built

OpenAI president Greg Brockman said that AI tools are now responsible for a much bigger chunk of software code than they were just months ago, sparking fresh debate about whether human engineers are increasingly becoming overseers rather than the main coders. Speaking at a Sequoia Capital event, he described how quickly the shift has unfolded. In his view, AI‑driven coding systems were behind roughly 20% of the code base around December, but that share has since jumped sharply, with machines now handling a far larger portion of the actual coding work than people realise.
