Mark Zuckerberg 'predicts' AI will write most of Meta's code within 12 to 18 months

Mark Zuckerberg says he believes most of the Meta’s code will be written by AI agents sometime within the next year-and-a-half. Zuckerberg made the prediction during an hour-long interview with podcaster Dwarkesh Patel.

“I would guess sometime in the next 12 to 18 months, we’ll reach the point where most of the code that’s going towards these efforts is written by AI,” said Zuckerberg, referring to the company’s efforts to build internal AI agents. “And I don’t mean like autocomplete… I’m talking more like you give it a goal, it can run tests, it can improve things, it can find issues, it writes higher quality code than the average very good person on the team already.”

Meta CEO, Mark Zuckerberg:

“within 12-18 months, most of the code is written by AI”

It won’t just be autocomplete.

This is not the first time Zuckerberg has made this type of prediction. During his awkward appearance on The Joe Rogan Experience earlier this year, he said, “Probably in 2025, we at Meta, as well as the other companies that are basically working on this, are going to have an AI that can effectively be a sort of mid-level engineer that you have at your company that can write code.”

Notice how the goal posts have moved. Less than five months ago, Zuckerberg said coding agents that could effectively replace most human programmers were within reach. Now, those same systems will not arrive by mid-2026 at the earliest.

The changing timelines underscore exactly why we should be critical of the AI industry and its many promises. AI agents may very well one day replace mid-level programmers, but right now predictions like the one made by Zuckerberg and many others are, at best, advertisements for technologies that don’t yet exist and may never perform at the level their advocates say they will.
