His stance is understandable, but hardly the best way to rally a team that needs to push current tech to the limit.
The real issue: Meta is *far behind* Google, Anthropic, and OpenAI.
A radical shift is absolutely necessary - regardless of how much we sympathize with LeCun’s vision.

According to Grok, these were LeCun's real contributions at Meta (2013–2025):
----
- PyTorch – he championed a dynamic, open-source framework; now powers 70%+ of AI research
- LLaMA 1–3 – his open-source push; he even picked the name
- SAM / SAM 2 – born from his "segment anything like a baby" vision
- JEPA (I-JEPA, V-JEPA) – his personal bet on non-autoregressive world models
----
Everything else (Movie Gen, LLaMA 4, Meta AI Assistant) came after he left or was outside his scope.
