a16z's Christian Keil Says AI Models Still Can't Build Hardware from CAD Files
Summary
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.
Key Points
- Keil says a master machinist still chooses stock, workholding and cutting strategy for each CNC part, which introduces translation errors.
- SpaceX is hiring 128 more employees with supply chain or related titles, Keil reports.
- Keil cites a friend whose chicken processing variance hit 20% week to week despite identical specs and machines.
