(Julio Elias vs. Al Roth)
...
"So it doesn't seem to me inevitable that Julio and his colleagues' arguments will lead, surely or soon, to a change in the laws banning kidney sales. And if kidney sales remain banned for a long time, other developments (such as cures for kidney diseases, or breakthroughs in using pig kidneys for transplantation) may arrive in time to make kidney sales, and human transplants themselves, unnecessary. This is one reason I have been putting my energy into developing kidney exchange: It's a way to combine economics with surgical know-how to achieve real gains soon. I'll be glad if something even better eventually becomes possible. It's good to attack big problems from all angles. Thanks, Julio, for the discussion."
