This is indeed what I thought he was saying, AI needs to dynamically learn, just training on static data sets is no longer enough to advance. So continuous learning is the future, and the best source of data for continuous learning is people themselves. Don't know what form that might take, instrumenting lots of people with sensors? Robots interacting with people? Self driving cars learning from human drivers? (already happening) Ingesting all video from surveillance cameras? Whatever form the input data takes, continuous learning would be an advance in high level AI. There's been work on it over the decades, not sure how that work might relate to recent LLM work.
