Physical robotics is scaling up hard. We're now seeing 14-foot humanoid platforms in the wild, and there's apparently a 20-footer in development somewhere. The engineering challenges here are brutal—inverse kinematics at that scale, actuator torque requirements, power distribution, and thermal management all become exponentially harder. The square-cube law means structural integrity and joint stress scale non-linearly. Most interesting question: what's the actual use case that justifies this form factor? Construction? Military? Or is this just flexing what's mechanically possible now that we have better motors and control systems? The bigger you go, the more you're fighting physics for diminishing returns unless there's a specific task that demands the reach and payload capacity.
