About this segment
Jeff Holden argues that conventional manufacturing physics fails at a few microns, and that chip fabs were built to make only transistors. That leaves micro machines, such as steerable brain robots, without a way to be manufactured.

“semiconductor manufacturing was invented to make one kind of machine, right? It's the semiconductor transistor and circuits built around that.”
Jeff Holdenat 2:20:27 · TBPN2:20:27Takeaways
- Macro-scale manufacturing breaks down at the low-digit micron scale
- Semiconductor fabs are optimized for a single kind of machine, the transistor
- Neurosurgeons want millimeter-scale robots that can be steered through the brain
