In 2013, Googles Sergey Brin separated from wife Anne Wojcicki, co-creator of DNA testing company 23andMe. The most obvious cause was a tangled Silicon Valley romance between Brin and Google Glass marketing manager Amanda Rosenberg, who was also dating then-Android VP Hugo Barra. At Vanity Fair, Vanessa Grigoriadis traces the story all the way back to Wojcicki and Brins first meeting, and to Brins discovery (via a 23andMe test) that he was at risk of developing Parkinsons disease. Grigoriadis blends Silicon Valley gossip with shades of Dave Eggers The Circle, saying that to some, the story is about the danger inherent in data sets, when the data includes too much information about ones mortality.
