>>14148449A true shittton in two fronts:
Physical: making actual devices which are able to move with the precision and finese that humans do would be so complex that you'd probably be better off using real life arms (cloned or harvested from brain dead people) and trying to connect into the brain.
Or if not, trying to make the best reproduction of a human body using synthetic materials. But we have no idea how to make muscle fibers so strong and flexible, joints so sturdy, but most important of all, the fact that it's self healing and self mantaining. How many times per day do you oil your elbows? 0 , it gets done automatically, same with all. Skin gets repaired automatically also, all of that is part of the human system
And if you managed to make all of that then there's the control aspect. Human movement is an insanely complex system to the point that it's not clear if part of the intellect is stored as muscle memory in the spine and even on limbs, when you grab a guitar for instance, the extreme amount of communication between a lot of different sensory systems which communciate simultaneously with different parts of the brain, commands muscles, has a lot of learned behvaiour of the feedbacks it expects and how to correct it plus capability to deal with unexpected feedback, and all of that is unavoidibly related to the unconcious mind which may be insanely complex, having been documented to be able to do weird shit like count seconds perfectly like a clock, extrapolate inmensely from little data, or just straight out know things no one has any idea how it knows
so yeah no, were not getting "human like" robots any time soon
