“Regenerative Medicine” has long been the holy grail as far as things on Doctors’ wish lists. The implications are staggering if we could master it. The blind would be able to see and the lame walk. All sorts of horrible injuries could be repaired. Worn out, diseased and damaged organs could simply be replaced. We’ve taken a few steps on the toward developing some replacement organs but we have a long way to go.
One thing this doesn’t note....if we could 3D print human organs we could also produce 3D printed meat. That doesn’t sound like a big deal but it would be huge if we could do it at a competitive price. Raising livestock is both financially expensive and environmentally expensive. Think of all the water used, all the feed, all the feces generated etc etc.
I’d call this technology, nuclear fusion and a cheap way to desalinate water the 3 most desirable inventions humanity could come up with in the next century.
Graphene is being looked at as a cheap, effective way to desalinate sea water. I’ll leave nuclear fusion to people a lot smarter than I am. Not that I have a low IQ but mathematics and physics are not my cup of tea
