我想有科学家正在尝试这样做，我希望他们能成功，这样世界会变得更干净，不是吗？如果他们发明一种东西，让我们每天只睡一两个小时，那就太好了。
I guess there are scientists right now trying to do that, and I hope they'll succeed because the world would be a much cleaner place, wouldn't it? I think it will be great if they invent something so that we only have to sleep for one or two hours every day.
如果真是这样，那就太好了，不过，真的可以吗？
博斯特罗姆：举个例子，如果我们能够在认知上取得些微进步，可以给我们多一点心智能量，或者防治类似老年痴呆这样的疾病，那就太好了。
