The book is not ‘about’ mathematics as such and nor does it apply mathematics to its subject. As a mathematician, though, what comes across is the author’s humanity rather than any application of mathematics. This is a popular mathematician’s take on the potential and actual impact of the rising use of algorithms on our current and possible future worlds.
