Why Humanoid Robot Prototypes Are So Hard to Build

The shared discussion points out:
- Building cars isn't a completely "greenfield" endeavor because vehicle forms and powertrains have mature foundations; humanoid robots, however, lack any ready-made paradigms to copy.
- Thus, the real challenge isn't just mass production, but getting the prototype right in the first place—and there isn't even a consensus on how to design one yet.
- The text draws an analogy to Tesla FSD: a long-term greenfield project that might hit many dead ends before finding the right path, and even then, the work is far from over.
