A breakdown of The Submillimeter Trap of Embodied AI, from First Principles Manufacturing, a newsletter by Yuanwei Ma at the intersection of AI, robotics, manufacturing and US–China.
Can the robots in today's AI demos do precision factory work like grinding and deburring? We take apart the argument: why "precision" is really two numbers that differ by 20x, how factories quietly turn an absolute problem into a relative one, what VLA papers never measure, and where embodied AI actually belongs on a precision line. Plus two thinking tools you can take to any robotics pitch.
