But given the very, very high levels of complexity today, no human being, and indeed, so far, no computer, is able to flawlessly model the entire set of variables and interactions that constitute a complicated system. One example I use is climate, where today we have very good models of climate, but they're absolutely simplifications of reality.
但是,鑑於今天的複雜程度非常非常高,沒有人,事實上,到目前為止,也沒有計算機,能夠完美無瑕地模擬構成一個複雜系統的全部變量和相互作用。我舉的一個例子是氣候,今天我們有非常好的氣候模型,但它們絕對是對現實的簡化。
