Leonardo da Vinci did not take received wisdom - whether from ancient classical thinkers or medieval scholars or from the Bible - without questioning it. And this was the beginning of the scientific method. This is another lesson for our time: that when we have evidence that contradicts a certain belief, we should be willing to change it. I think this made Leonardo, in some ways, a person who better understood the beauty of God's creation than a person who just takes all received wisdom from the Bible on faith.

I have my own theory about why decline happens at companies like IBM or Microsoft. The company does a great job, innovates and becomes a monopoly or close to it in some field, and then the quality of the product becomes less important. The company starts valuing the great salesmen, because they’re the ones who can move the needle on revenues, not the product engineers and designers. So the salespeople end up running the company.
