Okay what I meant was that a fetus that is viable has all the traits that make it qualify. In my opinion viability is the correct line. Viability is the ability to live outside the womb. Technology that attempts to cheat to act as an artifical womb doesn't change the fact that it isn't viable. Either way 90 something percent of all abortions and stem cell research use embryos. There is no way they come close to qualifying.
So what stage do you, personally, define viability at?
