Human fingertips and skin in general are extremely precise high resolution pressure and vibration sensors that robots almost completely lack. Tactile feedback takes up the second most human sensor bandwidth behind vision. Imagine doing anything without it- interacting with the world through a puppet.
The joints in a human arm are direct-drive series elastic actuators with pretty incredible sensitivity. If you were holding a big heavy box and I bounced a ping pong ball off it, you'd probably feel the vibration. That's kind of a big deal. You may not be able to measure absolute weight well, or even relative weight, but you can detect quick changes with amazing precision. Lifting any heavy or large object is inherently wobbly even for a robot, and that sensitivity is important.

Thousands of servos, millions of sensors, high-throughput compute AND all of that self-assembled and self-repaired AND built mostly out of water, carbohydrates and like 5 grams of iron. A meatbag is by far the best robot on the face of earth today, the gap is astonishing. My estimate is that we'll get AGI faster than human-capable robots competing with meatbags cost-wise. We'll have to deploy self-assembling robots throughout the whole supply chain from sand and ore to chips and servos, eliminate human salaries everywhere, only then the price will be comparable to a parent assembling and training a child which was the way for millions of years.
