把这一句，留给此刻的你
The killer app that got the world ready for appliances was the light bulb. So the light bulb is what wired the world. And they weren't thinking about appliances when they wired the world. They were really thinking about - they weren't putting electricity into the home. They were putting lighting into the home.
让世界为家用电器做好准备的杀手级应用程序是电灯泡。所以电灯泡连接了世界。当他们连接世界的时候，他们没有想到电器。他们真的在想——他们没有给家里供电。他们正在给家里装照明设备。
