How about the donor piggy though? If this becomes commonplace and animals are bred/raised just for their organs, we get into murky ethical territory. (Yes, people already eat the organs for food, that's murky too. But industrial scale organ farming sounds even worse somehow.)

some animals are more equal than others

I'm pretty sure a pig raised for donor organs will be better cared for than one raised for cheap pork chops...

“Xenotransplantation” is pretty #%^*ing metal. It’s pretty wild being alive these days. Lots of big stuff the species is struggling to adapt to and figure out how to exist with. But also… we got the tablets from Star Trek. And now we have the ship’s computer from Star Trek, and the early makings of the holodeck. And we’re making pigmen senior citizens who would otherwise be dead. It’s quite something to stop and thin…

And yet while (legitimate) science can universally agree continuing to burn fossil fuels will cause unimaginable chaos for planet earth, half the planet doesn't seem to care about the impending collapse. So while in my personal vacuum this is awesome, when I stop to consider the situation for 30 seconds I can only think: huh, we might have been able to find a new cure for humanity that isn't going to matter when havi…

Most experts don't predict the collapse of industrialized society. Higher temperatures, rising sea levels, and more energetic weather events will cause damage and make life difficult for decent chunks of the population especially those in less developed areas that are both hotter and more poorly equipped to cope with climate change. But I'm not aware of a consensus or even a plurality among climate scientists that industrialized society is going to collapse even in the more pessimistic predictions.

I'm not sure how Cambridge, Massachusetts, where the company building these pig kidneys is located, becomes a hunter-gatherer society on account of climate change.

The donor pig is turned into bacon. Normally the liver goes in the trash.

Asking out of ignorance. Why is the liver thrown out? Isn't it edible too?

That's genuinely impressive. Six months without dialysis after a xenotransplant is no small milestone, especially considering how many hurdles this field has faced over the years. The level of genetic modification involved shows how far biotech has come. Still, it's hard not to wonder about the long game. Immunosuppression, organ longevity, possible unforeseen complications - all big unknowns

Meanwhile we can’t figure out how to provide a basic level of housing and healthcare to everyone.

The US can't, but humanity as a whole can. Finland has both, for example.

Earlier quoted context omitted.

fwiw, biological heart valves, as opposed to metallic valves, are already quite commonly used today. biological ones are typically made from either cows, or pigs (bovine, porcine respectively). but this is on another level altogether.

But why cows and pigs and not chimps?

Presumably because we already farm pigs and cows so there’s a supply chain and the ethics are ok in most people’s heads.
