I think people will only accept 3d printed organs, pig and animal things are too controversial for some people.

I was listening to a podcast on the CBC about AI and consciousness, and the idea that humans are distinct from an animal (beastmachine, great name for a butcher shop btw) comes from Descartes, who we revere in philosophy (for fair reasons)..

I think we can't blame people for wanting to separate themselves from animals.
