Paul Knoepfler: The ethical dilemma of designer babies
基因改造听起来像科幻片里的情节，但就在11月26日，一则“世界首例免疫艾滋病基因编辑婴儿在中国诞生”的消息立刻在全球引发热议。
在一场标题为《定制婴儿的伦理困境》的TED演讲中，前沿细胞科学家Paul Knoepfler称，虽然基因编辑（gene editing）早已不是科幻小说中的情节，但只要第一个“定制婴儿”出生，几十年内，可能就会有上百万的基因改造人类出现。新的科技、新的风险、新的伦理道德价值观、新的一切……试想，那会是怎样的一个世界？来听听这场引人深思的演讲吧。
So what if I could make for you a designer baby?
What if you as a parent-to-be and I as a scientist decided to go down that road together?
What if we didn't?
What if we thought, " That's a bad idea, " but many of our family, friends and coworkers did make that decision?
Let's fast-forward just 15 years from now.
Let's pretend it's the year 2030, and you're a parent.
You have your daughter, Marianne, next to you, and in 2030, she is what we call a natural because she has no genetic modifications.
And because you and your partner consciously made that decision, many in your social circle, they kind of look down on you.
They think you're, like, a Luddite or a technophobe.
Marianne's best friend Jenna, who lives right next door, is a very different story.
