应对不自由世界的唯一方法就是变得如此绝对自由，以至于你的存在本身就是一种反叛。

I never write Metropolis for seven cents because I can get the same price for city. I never write policeman because I can get the same money for cop.

I have always considered that the true test of a machine is its practical utility in the hands of the common laborer.

有些人不喜欢改变，但如果替代方案是灾难，你就需要拥抱变化。
