A Los Angeles-based startup has demonstrated what it calls a breakthrough in hardware development: an artificial intelligence system that designed a fully functional Linux computer in one week — a process that would typically consume nearly three months of skilled engineering labor.Quilter, which has raised more than $40 million from investors including Benchmark, Index Ventures, and Coatue, used its physics-driven AI to automate the design of a two-board computer system that booted successfully on its first attempt, requiring no costly revisions. The project, internally dubbed "Project Speedrun," required just 38.5 hours of human labor compared to the 428 hours that professional PCB designers quoted for the same task.The announcement also marks the first public disclosure that Tony Fadell, the engineer who led development of the iPod and iPhone at Apple and later founded Nest, has invested in the company and serves as an advisor."We didn't teach Quilter to draw; we
