Here's a question that matters.[Is it ethical to evolve the human body?

这里有一个重要的问题。改造人体会出现道德问题吗？

Because we're beginning to get all the tools together to evolve ourselves. And we can evolve bacteria and we can evolve plants and we can evolve animals, and we're now reaching a point where we really have to ask, is it really ethical and do we want to evolve human beings? And as you're thinking about that, let me talk about that in the context of prosthetics, prosthetics past, present, future.

因为我们已经开始拥有改造自身所需的所有工具了。我们可以改造细菌，我们可以改造植物，我们也可以改造动物，我们现在已经到了必须要问这个问题的时候了，这是否会导致道德问题，或者我们是否想要改造人类？在你们思考这个问题的时候，让我就假肢为例子 和你们谈谈这件事，假肢的过去，现在和未来。
