Wiki Memory

The article introduces 'Wiki Memory' as a pattern for agent memory, where agents transform raw source data into a compact, persistent, and structured knowledge layer. Unlike RAG, it precomputes a higher-level synthesis. Examples include DeepWiki, Karpathy's LLM Wiki, and Factory's AutoWiki. The article also discusses open questions about raw data, compression format, and maintenance, concluding that files and agents are common answers.

Why Specialization Is Inevitable

This article argues that specialization is an inevitable consequence of finite resources and selection pressure, drawing from optimization theory (No Free Lunch theorems), evolutionary biology, competitive markets, and machine learning. It distinguishes specialization from domain knowledge and addresses the Bitter Lesson, concluding that scaling does not eliminate the need for focused systems.

The AI Productivity Trap

Many organizations report increased AI usage but struggle to see the expected impact on shipping. The author argues that the real value of AI lies in accelerating iterative shipping, not just generating more code. Engineers should focus on customer understanding and build verification loops to avoid the trap of low-ROI work.
