Discusses the trends of open vs. closed-source models and the true moat of the AI industry. The author suggests that closed-source labs may retain the cutting-edge capabilities, while open models will handle the majority of daily tasks. Once models are 'good enough', factors like price, reliability, data, and industry experience will outweigh marginal capability gains. Furthermore, security cannot be simply defined as 'open is dangerous, closed is safe'; different domains require different boundaries. The real AI moat might lie not within model weights, but in undiscovered and undocumented real-world information.
