I think this underestimates the incredible engineering of the human body. It runs at 100W, while retaining the ability to execute both very high torque actions and fine motor actions, with self-healing grip, and an ability to engage increasing numbers of muscles and the weight of the machine itself to accomplish tasks.
One thing I didn't quite realized needed teaching until I taught my daughter: how do you tell when a screw is going in right? It might have resistance because of gunk or rust, or it might be misaligned. Determining the right action is incredibly sophisticated, the difference between the slight easing of resistance with old oil or the springiness when the threads are pushing against each other and deforming. In response you might draw out and try again, or push harder, all while still trying to feel out what's really happening. Automation is great for screws in factories.
We don't have anything on the horizon that has the physical flexibility and power of a human. To the degree we can reconfigure problems to match a robot's capabilities, then yes, automation may be inevitable. A lot of problems aren't like that.
