Look on Their Works and Despair

Yeah, yeah, I know I'm a superstitious flatearther afraid of science and willing to impose my fear-based morality on others, but I'm beginning to wonder if our culture will be able to muster the fortitude to object to any scientific "advances." The latest:

Scientists have created the world's first human-sheep chimera - which has the body of a sheep and half-human organs.

The sheep have 15 per cent human cells and 85 per cent animal cells - and their evolution brings the prospect of animal organs being transplanted into humans one step closer. ...

The process would involve extracting stem cells from the donor's bone marrow and injecting them into the peritoneum of a sheep's foetus. When the lamb is born, two months later, it would have a liver, heart, lungs and brain that are partly human and available for transplant.

Are we just numb to this sort of thing at this point? Or do we live in a state of disbelief, as if the news were fiction? Or do we lack the imagination to envision the ways in which these trends can go horribly wrong, or the self-awareness to understand how the lines in the sand of our tolerance drift away with every gust of scientific presumption?
