Jeffrey Lee Funk posted that internal Meta data shows an AI shift drove code changes up 220 percent yet only 36 percent more features, major incidents up 40 percent, firefighting time up 70 percent, and favorable employee sentiment down from 74 percent to 55 percent. He linked a Reuters investigation. Bindu Reddy posted that Meta planned to replace engineers with AI agents for a 60 percent staff cut, that Zuck reversed course for a 10 percent layoff instead, that employees revolted, and that AI output produced 40 percent more security incidents. Both posts treat the figures as drawn from internal documents.
