Why do robots have to be humanoid? Could the biggest application for humanoid robots be as companions or for sex services? Wheels are clearly more stable, robotic arms are stronger, yet they insist on having arms, legs, a face, and expressions. Some say it’s because humanoid robots can directly adapt to human environments and operate human tools. That sounds reasonable, but if you think about it carefully, the logic doesn’t really hold up. It’s just a ‘sounds reasonable’ excuse. TK put it well: People can pretend, but money doesn’t. People in the AI industry pretend this won’t cause a wave of unemployment, and those being replaced pretend it’s still far away from them. Everyone is just acting calm. The real driving force behind humanoid robots is actually human psychology—we only trust things that ‘look human.’ AI voices need to sound human, robots need to walk like humans. Because only when they’re ‘like us’ will we let our guard down. Musk is working on Grok while building robots—it’s not two separate paths, it’s one straight line. Teaching machines to mimic the human mind is his true ultimate goal. When AI becomes human enough, humans will be more easily tamed by AI. — ‘Manzi Talks AI’ Xu Manzi AI Robots Grok Human-Machine Relationship
