Just take one long look at the kind of utter garbage human mind has to work with. It's a frame that, without a hideous amount of wetware doing data processing, can't even keep its own limbs tracked - because proprioreception is made of wet meat noise and integration error. Smartphones in 2010 shipped with better IMUs, and today's smartphones ship with better cameras.
Modern robot frames just have a different set of tradeoffs from the human body. They're well into "good enough" overall. But we are yet to make a general purpose AI that would be able to do "universal robot" things. We can't even do it in a sim with perfect sensors and actuators.
Read Brooks' argument in detail, if you haven't. He has spent decades getting robots to play nicely in human environments, and he gets invited to an enormous number of modern robotics demonstrations.
His hardware argument is primarily sensory. Specifically, current generation robots, no matter how clever they might be, have a physical sensorium that's incredibly impoverished, about on par with a human with severe frostbite. Even if you try to use humans as teleoperators, it's incredibly awkward and frustrating, and they have to massively over-rely on vision. And fine-detail manual dexterity is hopeless. When you can see someone teleoperate a robot and knit a patterned hat, or even detach two stuck Lego bricks, then robots will have the sensors needed for human-level dexterity.
