A few years back, I wrote an essay on the mental model of Redundancy. In that article, I mentioned how Bill Gates reasoned using Redundancy that saving lives in Africa will contain the country’s population growth over the longer term. One reader pointed out that Gates’ insight originally came from another guy named Hans Rosling.
A little bit of research revealed that Hans Rosling had a decisive impact on how Bill Gates thought about his philanthropy work in African countries. No wonder, when Rosling’s book came out, Gates was among the first to publish a review. He wrote —
Hans, the brilliant global-health lecturer who died last year, gives you a breakthrough way of understanding basic truths about the world—how life is getting better, and where the world still needs to improve. And he weaves in unforgettable anecdotes from his life. It’s a fitting final word from a brilliant man, and one of the best books I’ve ever read.
