the stem cell matrix (Score 1)

Perhaps this is a poor analogy, but everytime I read about stem cell research/ embryo farms, I think of the "robots" in "The Matrix" who harvested humans for power. To the robots, humans were nothing more than batteries. How is this any different than harvesting embryos for stem cells? Of course, we're uncertain of the moment life begins. Some contend that it isn't life until after birth. Well, my first child was 2.5 months early and he's now a healty 6 year old boy (who loves astronomy and strat-o-matic). Others contend that life begins at conception- typically a Christian sentiment. However, I contend that most people are honestly uncertain. So, is it ethical to enslave *possible* human lives for stem cell production? After all, it seems *fairly*(greater than 1%) probable (given the uncertainties of science) that these are indeed human lives. If you have solid proof to the contrary, I'd love to hear it. My current feelings are ambivalent.
