Meta's push to swap thousands of engineers for AI agents has broken down — bad news for Zuckerberg's credibility and for shareholders watching cash drain away, better news for workers worried their jobs are next.

• Meta cut 8,000 engineering jobs in May 2026, then froze a second, bigger round hours before launch when AI agents writing live code caused system failures to jump 40%.
• Code changes tripled while actual product improvements barely moved, forcing the remaining engineers to work harder reviewing AI-written code with AI tools.
• A staff leaderboard ranking who burned the most AI tokens turned usage into a performance target, costing the company well over $100 million with nothing to show users.
• Staff protests over keystroke monitoring killed the surveillance program, morale hit a 20-year low, and some engineers were moved back to their old jobs.
• The real driver was money: infrastructure spending jumped to $145 billion for the year, free cash flow collapsed, debt hit $83 billion, and share buybacks were halted.

Outlook: The layoffs bought only weeks of the buildout, so pressure on margins keeps growing, and the bigger risk is smaller companies copying a strategy Meta never proved works.
