The author uses Large Language Models (LLMs) to learn complex topics by asking the model to build a simulation game, which helps to visualize and understand the topic. The author provides an example of learning chip production by creating a simulation game called ChipTycoon. This approach is found to be more effective than reading endless materials or trying to digest bulleted lists generated by LLMs. The author also suggests ways to improve the simulation game, such as adding challenges and puzzles to help retain knowledge.
