The Path to AGI: Pure Transformer Scaling vs Grounded World Models
While Silicon Valley bets hundreds of billions on expanding autoregressive token models, Demis Hassabis and Yann LeCun argue from different angles that text prediction alone will never achieve genuine common sense or physical planning.
Demis Hassabis
CEO & Founder, Google DeepMind
"If you look at how human children learn, they don't consume 10 trillion words to understand gravity. They drop a cup. They interact with an actual dynamic environment."

Yann LeCun
Chief AI Scientist, Meta & Turing Award Winner
"A cat has a mental model of the world that allows it to pounce on a mouse. No current AI system has the common sense of a house cat."
