So are you saying bio-printing is good or bad? Or not saying.
As far as I can see, it’s a good thing. If you need an organ transplant, wouldn’t you much prefer to have one that’s bio-printed than one that is “harvested” from a dead person? It also seems to me that with bio-printing, you could get a custom printed organ that more closely matches you (maybe EXACTLY) thus eliminating or reducing the need for anti-rejection drugs that compromise your immune system.
Disclosure: I bought stock in a bio-printing company years ago. Not a lot. I think I’m in the red on it, but still holding it.
