With a couple extra fingers you could stir coffee or open an envelope with one hand.

The two doctored digits can hold a jam jar while the rest of them twist off the lid.
I think many people will have enhanced bodies in the near future. Better, longer-lasting members. (Sounds sexy). The rest of us will settle for our DNA recipe and a personalized set of stem cells that will renew our existing organs, keeping heart and skin in perfect health for the first hundred years or so.
The video is somewhat didactic as the Chinese-named undergrad and her Japanese-named supervisor use the gadget in a Massachusetts lab, but you can see how it could work and seem natural too.
