Modified pig hearts transplanted into dead people kept on life support

With a nationwide shortage in organ donations, these pig heart transplants are a successful step on the way to potentially helping hundreds of thousands of people in need of medical attention. While there is a long way to go, this is a promising sign.
There are clear ethical issues surrounding the concept of animal organ transplants. These include issues of animal welfare and breeding conditions, the scientific ignorance of the public, and some religious beliefs. Without a complete overhaul in public perceptions of this science, it will be hard for the process to become accepted in modern society.
There's an 80% chance that any human will live without the assistance of medical life support for at least 100 days after a transplant of a lab-grown organ before 2035, according to the Metaculus prediction community.
