BUILDING ON SAND: THE HIDDEN COST OF AI MODEL CHURN

Summary from the TLDR Founders newsletter

AI pushes technical complexity upstream into the problem space, where the PM lives. This means the PM must become the architect because architecture is now a product artifact. An AI model update can invalidate assumptions, making it impossible to define products, user experience, feasibility, or cost. The only way to build durable AI products is to design systems that assume the model will change.
