So a very quick summary of the main points I got from reading it were
- Proposing the use of a Gaussian distribution for assessing risk for real world events is ballocks.
- The events that you need to worry about are the ones you don't worry about
- Don't forget the positive black swans
- Few experts have any better insight into what disaster/wonderful opportunity may arise next and when it might appear
- Those who get predicting the future right are lucky
- Don't worry, it won't help much
There is a lot of distance travelled in the book, many stories told which add insight, but could have benefited from being a shorter book.
