Synthetic/bioprinted biological muscles are right around the corner (commercialization within 10 years). There are working proofs of concept today. There's also significant leap forward in soft robotics (not based on biology) - check out Keplinger Research Group.<p>I wouldn't bet on hands saving humans their jobs. My bet is on stuff that is "better" with the human touch - not objectively, but people just feel like that about some things. Mostly luxury items/services, and some classes of art.
