Should AI decide who gets a kidney?

Imagine this scenario: Two patients need kidney transplants, and there's only one donor organ available that both their bodies will accept. One is 60 years old but in good health, except for a bout with skin cancer that's now in remission. The other is 30, but a heavy drinker -- a risk factor for kidney recipients. The question of which patient should get the kidney is a thorny one, laced with judgments about age and lifestyle. Currently, decisions like it are often made by committees of doctors who weigh many factors, from a patient's age and medical outlook to the distance an organ would need to travel, in order to match a limited supply of donated organs with the long list of people waiting for a transplant.
