中文字幕比如一滴雨水和整个海洋尺度差得不可思议纳维–斯托克斯方程描述它们并不会因为从一滴水变成海洋原来的流体方程就突然失效或者水获得一种全新的“能力”但大脑和神经网络并不是这样“系统越大，能力越强”这件事数量更多以后，能力本身会发生变化“many more is more different”更大的大脑通常能支持更复杂的能力大脑也是如此所以核心就是尺度扩展（scaling）it's all about scaling神经网络真正重要的一点就是把它做大做大以后，反而会更准确、更不模糊规模差别巨大我们人类大约有一千亿个神经元而蟑螂只有大约百万量级and we're smarter than cockroaches网络规模变化以后它所能完成的事情可以发生定性的变化许多凝聚态系统根本不同的系统

英文字幕Because if I look at water in a raindropversus an oceanI can still use the Navier–Stokes equations.I can still use the same descriptionno matter how big it is.it doesn't work anymore for the oceans.but that's not true for a brainbigger being more powerful,“many more is more different”Bigger brains are better.And the same is true for brains, right?And so the whole key,it's all about scalingThe whole key to neural networks isto make them big, right?And they become actually less vaguewhich have 1 millionWe have 100 billion neuronsand we're smarter than cockroachesYou know, the kinds of things thatthey can do become totally differentfrom the kind of things
