When John Forbes Nash, the Nobel Prize-winning mathematician, schizophrenic, and paranoid delusional, was asked how he could believe that space aliens had recruited him to save the world, he gave a simple response. "Because the ideas I had about supernatural beings came to me the same way that my mathematical ideas did. So I took them seriously." Nash is hardly the only so-called mad genius in history. Even ignoring those great creators who did not kill themselves in a fit of deep depression, it remains easy to list persons who endured well-documented psychopathology, including the composer Robert Schumann, the poet Emily Dickinson, and Nash.

The video-game designer Shigeru Miyamoto once called the land of Hyrule "a miniature garden that you can put into a drawer and revisit anytime you like." Miyamoto conceived Hyrule, the setting for Nintendo's Legend of Zelda series, in 1986, and though its layout has changed often in the intervening decades, its ambiance of bucolic, occasionally threatening whimsy hasn't. Neither has the company's understanding of Zelda's essential purpose: to bring the great outdoors--the rollicking hills, the whispering caves, all that breezy, alfresco escapade--indoors. In recent years, Miyamoto, who is now sixty-four, has retreated to the position of Zelda's overseer, relinquishing control to younger directors inside the clandestine, Willy Wonka-esque factory that is Nintendo's Kyoto headquarters. But Hyrule remains indelibly his.

I've been thinking about the way The Legend of Zelda: Breath of the Wild, one of the best thing's Nintendo's yet made, reminds me of another game I played over a quarter century ago. I can't remember where, but at some point in early 1990 I read an interview with Richard Garriott--the same Richard Garriott (de Cayeux) now celebrated for catching a $30 million ride to the International Space Station in 2008. But in 1990, he was still better known as "Lord British," after a benevolent monarch who ruled over a fantasy computer domain Garriott dreamed up in the early 1980s. The interview concerned the sixth game in that series, Ultima VI: The False Prophet, a swords and sorcery romp that also, unusually for a video game, wrestled with themes like racism and xenophobia. It's been 27 years since I've thought about gargoyles and codexes and vortex cubes, thus I can't say how meaningful a story that seemed weighty then might come across now.

However, the "Ghost in the Shell" star is ready to end her marriage with Dauriac by filing for a divorce, which many believe will lead to a custody battle over their 3-year-old daughter, Rose Dorothy Dauriac. Johansson and Dauriac started dating in 2012. They eventually became an item, got engaged in 2013 and tied the knot on Oct. 1, 2014, after the "Avengers" star gave birth to their daughter. Unfortunately, two years after Johansson and Dauriac tied the knot, the couple split, US Weekly reported. The pair had been very private when it came to their relationship.

We saw a transition in the financial ecosystem from the Keynesian "animal spirits" of desk traders and investors to "microbe spirits" by computer algorithms simpler than animals or humans -- but just much, much, much faster. To understand these new phenomena we need a complexity approach. Econophysicists and financial gurus in complexity are no more in the fringe. What our work suggests is that since this war is already under way, and because from our paper it seems to correlate very well with observable crashes in the markets over timescales such as months, then any government watchdog/regulator charged with controlling their financial system also ought to have its own'troops on the ground'.» Not that this is wrong, but you can see that this level of competition would be very ferocious -- which is what happens in the markets.»

Do you think you can tell a piece of music composed by artificial intelligence (AI) from one created by a human composer? Before you read any further, let's find out. The following audio consists of two fragments, one written by AI, the other by a human. We're inviting 250 to exhibit at TNW Conference and pitch on stage! If you didn't get it right the first time, no worries--we'll have a couple more mini-quizzes like this below.

Kōshi Nakanishi began his career in video games on the Tenchu series at Acquire. He directed several games there, including Tenchu: Way of the Samurai and Shinobido: Way of the Ninja. He also directed What Did I Do To Deserve This, My Lord. In 2007 Nakanishi moved to Capcom and began working on the Resident Evil franchise. It was the first time he worked on a sequel, beginning with Resident Evil 5 as a game designer before being promoted halfway through that game's development cycle to direct Resident Evil Revelations on the 3DS. That game earned high marks from critics and gamers alike and led to his role as director of Resident Evil 7 biohazard.

We are well into 2017 and the situation hasn't got any better, so here comes the routine alert from world-renowned theoretical physicist Stephen Hawking that we're all gonna die -- and it's all our fault. SEE ALSO: Smart people everywhere celebrate Stephen Hawking's 75th birthday During an interview with The Times, Hawking repeated the concept that humanity faces existential threats from climate change, artificial intelligence and mass species extinction. "Since civilisation began, aggression has been useful in as much as it has definite survival advantages," he said. "It is hardwired into our genes by Darwinian evolution. "Now, however, technology has advanced at such a pace that this aggression may destroy us all by nuclear or biological war," he continued. "We need to control this inherited instinct by our logic and reason.

Artificial intelligence is shaping up as the next industrial revolution, poised to rapidly reinvent business, the global economy and how people work and interact with each other. Andrew Ng, chief scientist at Chinese internet giant Baidu Inc. and co-founder of education startup Coursera, and Neil Jacobstein, chair of the artificial intelligence and robotics department at Silicon Valley think tank Singularity University, sat down with The Wall Street Journal's Scott Austin to discuss AI's opportunities and challenges. What is Baidu focused on? NG: For large enterprises like Baidu, AI creates two big pockets of opportunities. One is our core business.
