Crossing the River by Feeling the Stones
summary
Uses Wardley Mapping to turn assumptions into positions on a map, exposing a custom‑rack detail that saves about £8 million in 5 minutes and a government replan that avoids ~£425 million of waste; maps decide what to outsource by matching evolution stage to method (XP left, Lean middle, Six Sigma right). Shows vibe coding and conversational programming prototypes that produce a fake testing‑engine simulator (coherent but untrue), warns that large language models embed unseen cultural values and create digital‑sovereignty risks.
