a16z's Christian Keil Says AI Models Still Can't Build Hardware from CAD Files
Christian Keil argues in an a16z essay that AI models still cannot carry a hardware design from CAD file to assembled part, because translating bits into atoms and back stays lossy. He cites tests of OpenAI's Astra, Anthropic's Fable 5.1 and Grok 4.6 on his LuxoBench lamp project. SpaceX lists 591 supply chain employees.
