Karpathy's observation on human cognitive decline highlights the need for exposure to new and diverse experiences to prevent stagnation in thought and creativity. The author shares personal strategies to maintain mental freshness, such as reading widely and using AI to enhance language and content novelty. Emphasizing the importance of entropy in life, the article advocates for constant novelty to combat predictability and intellectual collapse.

• Karpathy argues human cognition can stagnate over time without fresh input, similar to model collapse in AI trained on its own outputs
• The author counters this by deliberately reading widely outside familiar topics to stay mentally fresh
• The author uses AI tools to inject novelty into language and content rather than relying on repetitive personal patterns
• Deliberate exposure to entropy and unpredictability is framed as a defense against intellectual and creative decline
