Self driving cars started appearing after Darpa 2005. Even after 21 years we don't have fully self driving cars around the world. And Driving is a "easier" robotics problem compared to other robotics problem.

Human body is far more complex than human brain. The real world is far more complex than our artificial world of "concepts" that these LLMs are dealing with. Robotics company are showing a robot working in a clean environment not the edge cases. Real world is all about the edge cases. I think humans(animal) can perform in real world is because we have biological instincts(survival, reproduction etc) which are missing from these machines. And maybe machines need this instinct to flourish in real world.

Code is a easy problem as it can be verified. I would be amazed with AI can write a good short story.
