theodp writes Silicon sultans are the new robber barons, writes The Economist, adding that "they have been diversifying into businesses that have little to do with computers, while egotistically proclaiming that they alone can solve mankind's problems, from aging to space travel." Over at Slate, NYU journalism prof Charles Seife is less-than impressed with The Billionaires' Space Club. "It's an old trick," begins Seife. "Multimillionaires regularly try to spin acts of crass ego gratification as selfless philanthropy, no matter how obviously self-serving. They jump out of balloons at the edge of the atmosphere, take submarines to the bottom of the ocean, or shoot endangered animals on safari, all in the name of science and exploration. The more recent trend is billionaires making fleets of rocket ships for private space exploration. What makes this one different is that the public actually seems to buy the farce." Seife goes on to argue that "neither [Elon] Musk's nor [Richard] Branson's goals really seem to break new ground, despite all the talk of exploration."
