Designer Babies

I'm concerned about the potential for "saviour siblings" and the relaxation of the rules which MPs are apparently calling for. "Saviour siblings" is a highly biased way of describing these babies, it makes it sound all very cuddly, innocent and positive. Of course "designer babies" is equally as biased and has less positive connotations. The idea sounds positive enough, allow embryoes to be developed which will help to cure illness in children. But what is the cut-off? What will happen if the babies born turn out not to be as helpful as had hoped? What is the extent of their usefulness? Blood transfusions? Gene therapy? Organ harvesting?

To me this is a dangerous precendent to set and there are many, many more questions to be answered before such a move could be allowed.

Babies are not a commodity be it in monetary or genetic terms.
