The AI Leadership Shakeup: LeCun’s Departure and Wang’s Arrival

The Departure: Yann LeCun

  • Chief AI Scientist → Departed
  • Turing Award Winner (2018)
  • 12 years at Meta
  • Founded FAIR (2013)
  • Godfather of Convolutional Neural Networks

→ Launching AMI Labs ($3.5B valuation target before launch)

The LeCun Thesis

  • V-JEPA architecture (not LLMs)
  • Learning from video & spatial data
  • Physics and world understanding
  • 5-10 year research horizon

“LLMs are a dead end for superintelligence”

The Arrival: Alexandr Wang

  • New Chief AI Officer
  • Founder & CEO of Scale AI
  • Youngest self-made billionaire (was 25)
  • $14.3B Scale AI deal with Meta
  • Data infrastructure & AI operations expert

Execution over research. Scale over exploration.

The Context: Llama 4 Debacle

  • Benchmark gaming admitted by Meta
  • Public embarrassment in AI community
  • Research credibility damaged
  • Timing: right before LeCun departure

Signal: Research culture concerns → Shift to execution-focused leadership

The Fundamental Fork

Dimension LeCun/AMI Meta/Wang
Architecture World Models LLMs (Llama)
Learning Video, Physics Text at Scale
Timeline 5-10 years Now
Focus Research purity Commercial scale
Investment $3.5B (target) $72.2B (2025)

“Execution over research, scale over exploration, LLMs over world models — Meta has made its bet. The infrastructure moat is the hedge.”
