Im no Nostradamus. Neither was Nostradamus, come to think of it. But one doesnt need to be to see how ethically icky, in the professional vernacular, the future of medicine is going to be.

To paraphrase Captain Kirk, our medical tools are growing faster than our wisdom. The future isnt now, yet, but its closer than we realized. And almost certainly closer than were ready for.

Consider the case of the Al Sabbagh family. They recently arrived in Canada from Syria, with their children, including their son, Mohamad. Mohamad is 10 and suffers from idiopathic aplastic anemia, a rare condition. Mohamad has a severe case, and it would likely be fatal if untreated.

His illness has left his body incapable of producing blood cells necessary to remain healthy. According to a report in the CBC, he requires twice-weekly blood transfusions at the Hospital for Sick Children in Toronto. Even with those, his quality of life has absolutely been impacted.

Theres a chance for Mohamad to live a healthy, normal life. A bone marrow transplant could restore his ability to produce the blood cells he needs. But the donor must be a very, very close match. Mohamads parents are not optimal donors, neither are his siblings. Its also possible to seek a donor through public donor banks, but you want as close a genetic match as possible.

Canadas Arab population is relatively small, and the number of those Canadian-Arabs whove put their information into a donor registry is even smaller. The odds for young Mohamad are long.

Thats led his parents to consider a remarkable step. New embryos could be created, using in vitro fertilization techniques, using the genetic material of his parents. The embryos can then be genetically screened, with only the best match implanted into Mohamads mother for gestation and delivery. That baby could then be used to provide a potentially life-saving transplant of stem cells into Mohamad.

If all went well, Mohamads bone marrow would regenerate, curing his illness. The infant would not be endangered (the donor cells would be collected from the umbilical cord blood, not the infants body).

There aretwo equally valid ways of looking at this. Indeed, they should go hand-in-hand. As a father of two young children myself, I cant fault the Al Sabbaghs for wanting to save their son, at any cost. If my children were suffering and this was the best chance to cure them, I wouldnt hesitate to sign on whatever dotted lines were required. Adding a third child to our family would be a blessing. I confess to not consulting with my wife before writing that, so dont blow my cover, but if thats what it took, I know wed be on board.

But on the other hand, how can it not send chills down your spine to think of creating a human being purely to benefit someone else?

This is not a criticism of the Al Sabbaghs, nor of any other family that has previously conceived a so-called saviour sibling. I 100 per cent understand the urge to save the child you have. Theres no moral blame here. But good Lord, what a strange path were embarking on.

A few decades ago, this wouldnt have been possible. The Al Sabbagh family would have had limited choices.

Bone marrow transplants have been around since the 1970s, but the ability to conceive multiple children, genetically screen them for compatibility and then bring specifically the best match to term, is much newer. Its a small peek into a future were just arriving at.

Medical technology is advancing rapidly, and stem cells are a particularly promising field. But as we push these technological envelopes, were going to encounter tough moral dilemmas that we are not ready for. Indeed, we probably havent even thought of them yet.

Im not a medical ethicist, nor an expert in the field of stem cells and transplantation. But one doesnt need to be to wonder about the morality of creating a person to save another. Even if the saviour sibling lives a long, healthy and happy life, cherished by its parents and the brother it saved, you cant help but wonder what psychological toll it would take knowing you were, at birth, essentially raw materials. And its also not too hard to envision a future where this treatment could be used more broadly, with new life being created simply to cure the injuries and illnesses of those already living.

After all, why not? Dont the needs of the sick and dying today take precedence over people who only exist in theory?

It seems wild now, like something out of science fiction. But our sci-fi daydreams have a habit of becoming reality. Are we ready for what this would mean? Are we prepared for a future where children can be conceived and harvested for parts? Would we feel better if the raw material babies were genetically tweaked in such a way that they never developed consciousness, and were therefore something less than human? Would it soothe our consciences to breed human tissue to serve just as spare parts if the bodies never grew a brain?

None of this matters much for Mohamad, a 10-year-old boy lucky enough to be born in a time and now live in a place where modern medical miracles make curing his brutal illness possible. And no one should judge the desperation of a mom and dad who just want their son to live a long, healthy, normal life.

But consider this a case study, a sample of the future. We are moving into new frontiers in leaps and bounds. I hope to hell were ready for the questions well face once were there.
