While AI is helping coders produce code faster, it may not be producing better code, researchers warn. And that could cause problems down the road for them.
In 2026, you cannot pry AI coding tools out of developers’ vise grip, researchers have discovered.
But while AI is undoubtedly helping coders produce code faster, it may not be producing better code, other researchers warn. And that could cause problems down the road for them.
Specifically, in February 2026, respected AI research lab METR published a surprising revelation: Most developers won’t work, even on a limited number of tasks, without AI anymore.
METR had hoped to provide an update to some groundbreaking research published a few months earlier, in 2025, on AI coding productivity. In it, researchers measured how much time open source developers took to do tasks by hand versus with AI.
While developers in that study reported that AI was making them more productive, they were shocked to learn it actually slowed them down. Sure, it generated code faster, but then they spent extra time finding and fixing errors, steering the AI and waiting on it to complete tasks.
When METR set out to repeat the experiment to measure advances in AI and coder proficiency, they couldn’t.
