A four-year-old has seen more of the world than ChatGPT. Yann LeCun is betting $1bn on that

Yann LeCun, a pioneer in AI and former Meta chief AI scientist, has left Meta to start a new company called AMI with a $1 billion seed investment. He argues that large language models like ChatGPT, while effective with text, lack true understanding of the physical world and cannot perform tasks that even young children or animals can. LeCun's approach focuses on building "world models" that better represent and predict physical reality, addressing limitations he sees in current AI methods.
