What Should We Be Worried About?

The Edge Foundation, an association of science and technology intellectuals, offers an annual question to its members. The 2013 Edge Question was: "What should we be worried about?" This audiobook consists of more than 150 brief responses by science intellectuals--prominent and obscure. The essays are best enjoyed a handful at a time. The ensemble of narrators is excellent. Their pace is good, their diction is clear, and they have little difficulty with the sometimes challenging technical vocabulary. Peter Berkrot, perhaps, sounds a little too much like the narrator of a negative political ad. This will bother you only if you listen to too many essays at once.
