I want to make you aware of this great blog entry that is named similar as this posting. The author (Tim Urban) goes a lot deeper than many other articles that I have seen on this topic. It is a homage to Elon Musk and his Tesla company, but you get a lot more out of it. Having known most of it I am still impressed. Well researched, nicely elaborated on the context, skilfully put together.
Why am I so impressed by this article? Because the article goes way beyond the usual superficial answers. It is the best application of the “5 Whys Model” that I have seen so far. The outset of the article is about the Tesla car company. But to provide the full understanding of the material the author goes back to evolution.
The authors blog is worth looking at.
