I think I've mentioned before my father always used to say, "you can fight nature but the best you can hope for is to come second". Stem cell research will be useful but again there will be a downside. Big companies and governments will promote the technology for not necessarily noble purposes. But we have to live with that. I'm not actually that much against gene transfer. Caution of course.
