In retrospect, he said, the “trajectory of the agentic development over at least the last four months hasn’t really accelerated in the way that we expected,” and that the company’s bets on the new structure “haven’t come to fruition yet.” Zuckerberg was referring to AI agents, automated systems that can execute tasks on behalf of a user.

Conversations he was having “with our top people” when they started planning the restructuring in January and February “were that they were worried that we weren’t going to move fast enough to adapt,” Zuckerberg said.

If Zuckerberg is seeing problems, that means other large tech firms that also followed the siren call of AI transformation and opted to quickly shake things up are likely feeling similar pains.

For instance, Andy Jassy spouted very similar language in his 2025 letter to Amazon shareholders (https://www.aboutamazon.com/news/company-news/amazon-ceo-and...) which was followed by layoffs (https://news.ycombinator.com/item?id=46748603).

What have we seen since? Lots of stuff breaking, from seller-focused tech (https://sellercentral.amazon.com/seller-forums/discussions?s...) to cloud services. Amazon now mandates senior engineers to sign off on AI-generated code (https://news.ycombinator.com/item?id=47323017), even though that will interfere with the mandate to "move fast and operate the like the world's biggest startup."

This will never work because then you are expecting the more experienced people to be reviewing endless slop coming from less experienced people. They will either do a bad job to comply or just quit
