Thinking in Systems, Shipping in Loops

AI has removed the typing from software engineering & left the system design. DHH told Rails World that writing code by hand is no longer economically productive ; Artemis engineers merged 16 pull requests per day by August, & Lauren Tan ships 2,000 a month. The craft of fitting code together by hand is over ; what remains is designing the loop that decides whether the output is right. Donella Meadows's three properties of great system design, resilience, self-organization & hierarchy, describe how those loops are built. The architect's drafting table was always scarce because the foundation was scarce, not the talent.
