Peter Norvig on AI, programming, and the recent leap in LLM capability
In this talk, Peter Norvig reflects on the future of AI and programming, focusing on how quickly language models have improved from producing imperfect code to generating practical, efficient solutions and stronger reasoning. He uses examples from programming tasks and logic puzzles to show the gap between 2024 and 2025 capabilities, and argues that AI may be reaching a threshold where usefulness becomes broadly apparent. The discussion also returns to broader questions about language, written knowledge, and the data scale that made modern systems possible.
From rough code to stronger programming assistance
Norvig contrasts earlier code-generation results with newer 2025 tools that produce cleaner, more efficient, and more useful programs.
Better reasoning and problem solving
He discusses how models are improving at solving logic and theory-of-mind style puzzles, including the Cheryl’s birthday problem.
A threshold that changes adoption
The talk frames current progress as a possible threshold moment, similar to the adoption curve he saw in speech recognition.
Language, data, and long-term AI progress
Norvig reflects on the role of the written word and how large-scale training data changed what AI can learn from language.

language models. So what does that mean? So theory of mind means can the language model think about not only what it knows but also think about what other people knows and the difference between what it knows and what somebody else knows. And so I asked it to solve this logic puzzle called the Cheryl's birthday puzzle. uh
