Developer @markovsrazor built a working simulation of the Computer Mark I, an analog fire control computer used during WWII.
The entire simulation was generated in one shot with Claude Opus 5.5, using only the original 300-page 1945 US Navy manual — no iterative debugging required. The tweet sparked discussion about where such capabilities are heading.
