Pasting in comments from a personal thread where friends discussed the book. Forgive the informal language:

The guy (a physicist) basically interviews people he finds interesting. Some of it is pure crap, other interviews are dated (interviews took place between 2002 and 2009, and there have been changes to theories regarding the multiverse, for example). However others, especially those that pertain to parenting and primates, are interesting and somewhat timeless.

The interviews range from astrophysicists to holistic medicine proponents to primatologists. The interviewer (and most subjects) are German, which is very entertaining to me, as all of the stereotypes are made out to be true :).

The quote below (along with some others from the same interview on motherhood and parenting) really made me think. I had not considered how birth control allows women to attain status/power/ wealth before having kids.

"With the availability of safe and reliable birth control, women can vote with their ovaries, opting for improved status or subsistence while delaying childbirth or avoiding it altogether, or delaying until they find themselves in a more supportive situation. Which is enormous progress: In the past, women who were at the end of their rope abandoned their children—as in the tale of Hansel and Gretel. Such behavior was much more frequent than most people realize. In Tuscany, for example, between 1500 and 1700, at least 12 percent of all children were left at orphanages."

Overall, this is an interesting collection of interviews with people who clearly love their work. If you like what are basically Vanity Fair-style interviews with some very smart (and in some cases very out there) people, pick this up. Richard Dawkins' interview is REALLY dated, however. His statements came the closest to actually pissing me off, and he even notes in the interview that he should have phrased some things differently when The Selfish Gene was first published.
