“The thing you have to understand about exponential growth is that it feels like nothing is happening for ages and then it’s like an unstoppable truck that’s just slamming into a wall.”
Her favourite example is of an imaginary liliy pad on a pond doubling its area every day. It starts growing in one minuscule corner and covers the whole surface of the pond after a month. By day 20, the lily pad is still almost invisible. By day 28, it covers a quarter of the pond, by day 29 it covers half, and by day 30 it covers it all.
