I would be lying if I said that I knew, one year ago, the meaning of a caption "This pig could save your life" in the National Geographic magazine this May. Now we know. And more so after the headline from the scientific journal Nature yesterday, announcing the news "Amazing feat: US man still alive six months after pig kidney transplant." And surprise, surprise, there have also been stories of pig heart transplantation in human body.
The scientific breakthrough of genetically modified pig kidney is unparalleled. No one can argue with the enthusiasm. And yet, the impact is still beyond our imagination. Anything can go south. Any time.
For a start, there is never a guarantee that xenotransplantation will halt the global donor shortage overnight. This brings me to the idea of researcher Roy Amara. Amara's law, which I learned recently, stated that as a society we often overestimate how technology will change the world in the short run and undersell its effect in the long run.
So, in all likelihood, pigs will more often appear on our dining table than in hospitals for the time being. And finally, dialysis will either disappear or simply serve as a bridging therapy, when pig kidneys are powered by major revolutions ten years later.
