These would later come to be known as von Neumann machines.

这些后来被称为冯·诺依曼机器。

In the context of space exploration, von Neumann machines could be built on Earth and launched into space.

在太空探索的背景下，冯诺依曼机器可以在地球上建造并发射到太空。

Creating von Neumann machines would require a few technologies we don't have yet, including advanced artificial intelligence, miniaturization, and better propulsion systems.

创造冯诺依曼机器需要一些我们还没有的技术，包括先进的人工智能、小型化和更好的推进系统。

Scholars crunched the numbers and found that a single von Neumann machine traveling at 5% of the speed of light should be able to replicate throughout our galaxy in 4 million years or less.

学者们对这些数字进行了计算，发现以 5% 的光速行进的单个冯·诺依曼机器应该能够在 400 万年或更短的时间内复制整个银河系。

In fact, in Brin's story " Lungfish, " some von Neumann machines are keeping a close watch over the Earth right now, waiting for us to reach a certain level of sophistication before they make their move.

事实上，在布林的故事“肺鱼”中，一些冯·诺依曼机器此时正密切注视着地球，等待我们达到一定的复杂程度再采取行动。
