Meta's engineering organization, once legendary for its 'move-fast-and-break-things' culture, is experiencing a dramatic breakdown according to Gergely Orosz's Pragmatic Engineer Newsletter. For two decades, engineers enjoyed a profit-center status with minimal processes and strong product focus, epitomized by the company's famous 'little red book' of engineering mantras. The culture shifted toward stability in the early 2020s while maintaining engineering-centric values.

The transformation accelerated after Meta pivoted heavily into AI, acquiring Scale AI for $14.8B and installing its CEO Alexandr Wang to lead AI strategy. Engineers report being pressured to use AI constantly, feeling undervalued, and witnessing embarrassing outages. What was once a celebrated workplace for software engineers has reportedly become a cost-center viewed with disdain by leadership, representing a stark reversal of the company's historical approach.

Meta's AI ambitions follow missed opportunities in mobile platforms during the 2010s, driving massive investments in VR/AR and now large language models. The company released Llama models from 2023-2025, but Llama 4 disappointed, forcing a rebuild from scratch. This shift from product-focused engineering to AI-first mandates has created internal turmoil and confusion among veteran engineers who built Instagram's battle-tested infrastructure and launched Threads to 100 million users in a week.

The contrast with other Big Tech firms is striking - unlike Apple, Google, Microsoft, and Amazon which all own hardware platforms or operating systems, Meta lacks this foundation. Now it's betting everything on AI while dismantling the very engineering culture that made its platforms successful. Whether this strategic pivot will pay off remains uncertain given the internal chaos and talent exodus reportedly underway.
