EPISODE DESCRIPTION
Yann LeCun is the chief AI scientist at Meta. He joins Big Technology Podcast to discuss the strengths and limitations of current AI models, weighing in on why they've been unable to invent new things despite possessing almost all the world's written knowledge. LeCun digs deep into AI science, explaining why AI systems must build an abstract knowledge of the way the world operates to truly advance. We also cover whether AI research will hit a wall, whether investors in AI will be disappointed, and the value of open source after DeepSeek. Tune in for a fascinating conversation with one of the world's leading AI pioneers.

EPISODE SUMMARY
In this episode of Alex Kantrowitz, featuring Alex Kantrowitz and Yann LeCun, Why Can't AI Make Its Own Discoveries? — With Yann LeCun explores Yann LeCun on why LLMs can’t discover—and what’s next Yann LeCun argues that large language models mainly learn to produce text matching training statistics, making them strong at retrieval but fundamentally limited at inventing new solutions or asking novel research questions.
