While there are concerns regarding this technology, the benefits far outweigh the risks on this issue. For those who fear this could lead to a dangerous explosion in human cloning, that technology has been around for 25 years and the cloning apocalypse still hasn't happened. Synthetic embryos will give the hundreds of thousands of women dealing with pregnancy complications a safer alternative, so this option deserves extremely serious consideration.
Just because something is scientifically possible doesn't mean we should do it. Mothers and fathers are supposed to create babies together, and mothers carry them in their wombs — just as every other animal does — because it builds an unmatched connection between parent and child. Without a natural conception and birthing process, the start of human life could be mechanical and robotic rather than beautifully willful.
