Meta's AI Leadership Under Fire: Ex-Chief Scientist Slams 29-Year-Old Billionaire's Role

• Former Meta Chief AI Scientist Yann LeCun criticized Meta's AI leadership, warning of potential employee departures.
• The controversy stems from 29-year-old Alexander Wang joining Meta as Chief AI Officer in 2025, despite his perceived inexperience in research.
• LeCun highlighted the Llama 4 benchmark controversy, which reportedly shook Zuckerberg's confidence and sidelined the Gen AI division.
• He argues Meta's focus on "safe" paths stifles innovation and believes LLMs are a "dead end" for superintelligent AI.
• LeCun has started Advanced Machine Intelligence Labs, focusing on "world models" that learn from physical data, not just text.

Why It Matters: Meta's AI strategy faces internal criticism over leadership, innovation, and the future of large language models.
