According to the 1999 film Bicentennial Man, society is about 40 years away from fully-functioning artificial organs. But according to science, the timeline might be a little shorter. Bicentennial Man follows the journey of a robot intent on becoming human, so much so that he studies medicine to build artificial organs for himself (which are also used by humans). Researchers at Case Western Reserve University are hoping to have a human-scale version of an artificial lung in clinical trials within a decade, and did we mention the machine that can print out organs? That’s coming along as well.
