Humanoid Robots Lag AI for Three Reasons

A fully automated economy is further off than cognitive AGI because of three bottlenecks: robotics AI is far behind (roughly GPT-2 level at physical manipulation, since ~90% of our neurons are dedicated, evolution-hardwired motor-control engines making 'easy' tasks computationally hard and data scarce); robotic hands still lack human dexterity and touch; and there are only thousands of inferior humanoid robots versus 8 billion biological ones, so even after solving AI and hardware, physically building billions of robots adds years.
