Geoffrey Hinton
Geoffrey Hinton
Overview
Section titled “Overview”Geoffrey Hinton is widely recognized as one of the “Godfathers of AI” for his foundational contributions to neural networks and deep learning. In May 2023, he made global headlines by leaving Google to speak freely about AI risks, stating a 10% probability of AI causing human extinction within 5-20 years.
Hinton’s advocacy carries unique weight due to his role in creating modern AI. His 2012 AlexNet breakthrough with student Alex Krizhevsky ignited the current AI revolution, leading to today’s large language models. His shift from AI optimist to vocal safety advocate represents one of the most significant expert opinion changes in the field, influencing public discourse and policy discussions worldwide.
His current focus emphasizes honest uncertainty about solutions while advocating for slower AI development and international coordination. Unlike many safety researchers, Hinton explicitly admits he doesn’t know how to solve alignment problems, making his warnings particularly credible to policymakers and the public.
