Yes, it is very creepy stuff. I thought that it wouldn't happen at least for another 20-30 years.
The implications of an artificial womb affects the abortion debate in a big way.
We had a debate on this very subject in one of my Philosophy/Logic classes in college.
At that time an artificial womb was something that only existed in sci-fi. But it was discussed as a very probable medical breakthrough in the debate. "What will happen when babies can survive out of the womb before the third trimester or just after the time of conception?" "How will the medical profession re-adjust their definitions about the beginning/viability of life." I thinkg that the bar has just been moved back to an undifferentiated embryo.
As it stands now, the maximum date for an abortion is directly proportional to the minimum amount of time that a fetus needs to develop lungs in order survive outside the womb on it's own. Now, if this artificial womb exists, there will be no real excuse, reason, set of rules or minimum time limit to terminate a pregnancy. The embryo, potentially, could survive outside the mother at any time after the conception.
The whole abortion debate could instantly become moot. Mothers will not have the choice of bearing unwanted children. Doctors can just remove the embryo and continue the pregnancy sans the mother.
The new debate will be about what to do with all of those embryos. "Potentially billions, just in our country alone."
