robot dexterity and cognition are both very very hard problems. Once we solve that, we just don't get human hand equivalents. We can make very tiny hands that can manipulate cells and perform intricate surgeries, or huge hands, that can move boulders and build a house in a day, or hands with 100s of snake like fingers manipulating 100s of things simultaneously and running a click farm. Once we can build artificial brains more powerful than humans, and artificial muscles more dexterous than humans, almost every profession is at risk. In addition if machines are not made in a factory, but replicated organically like seeds because we figured out the magic DNA, then we've essentially created von-neumann probes and can conquer the rest of the galaxy.
