Robin Hanson thinks the robot takeover, when it comes, will be in the form of emulations. In his new book, The Age of Em, the economist explains: you take the best and brightest 200 human beings on the planet, you scan their brains and you get robots that to all intents and purposes are indivisible from the humans on which they are based, except a thousand times faster and better. Related: The Guardian view on artificial intelligence: look out, it's ahead of you Editorial For some reason, conversationally, Hanson repeatedly calls these 200 human prototypes "the billionaires", even though having a billion in any currency would be strong evidence against your being the brightest, since you have no sense of how much is enough. But that's just a natural difference of opinion between an economist and a mediocre person who is now afraid of the future. These Ems, being superior at everything and having no material needs that couldn't be satisfied virtually, will undercut humans in the labour market, and render us totally unnecessary.

Learning machines are capable of working ever more autonomously on ever more complex tasks. In this blog, Muz Janoowalla explores whether it would be smart for humankind to develop an'intelligent gun'. There are an estimated 875 million civilian, law-enforcement, and military firearms in the world, of which 650 million are in the hands of civilians, either legally or illegally. Given the plethora of high-profile gun attacks in recent months and years – particularly in the US, but also in France, Norway, Pakistan and Tunisia, to name but a few – it is disturbingly easy to imagine gunmen on the loose in a school or at a public event, shooting indiscriminately and leaving casualties in their wake. Imagine how different things could be if a gun had artificial intelligence built into it, turning it into an intelligent gun.

Senior White House adviser Valerie Jarrett is still listing "ending two wars" as one of the major accomplishments of the Obama administration, despite deepening U.S. involvement overseas – including the recent U.S. drone strike that took out Taliban leader Mullah Mohammed Akhtar Mansour. Jarrett, one of President Obama's closest aides, made the remarks in an interview aired Sunday on CBS' "60 Minutes." Asked whatever happened to the president's call for "hope and change," she cited a slew of changes during Obama's two terms: "Just look at what's happened in the last seven years. While the interview may have been conducted before the official Pentagon announcement, her comments coincided with the news that a drone strike had taken out Taliban leader Mansour in the Pakistan province of Baluchistan – the latest sign of the prolonged fight in the Middle East and South Asia. Even before those comments, the administration was taking criticism for efforts to downplay U.S. military actions against terror and insurgent groups.

Earlier this year, the Institute of Electrical and Electronics Engineering's (IEEE) published "AI's 10 to Watch" – a list of 10 people who are doing phenomenal work in the field of artificial intelligence. A Pakistani researcher Haris Aziz, who had graduated from LUMS, had his name published in this prestigious list for his work in the field related to computational social choice, an intersection between artificial intelligence and economics. Its seems that was just the beginning of the road for Haris Aziz, who is now back in the news for solving an'unsolvable' mathematical situation. Who will get the larger share of the profit from a business? Shall it be equally allocated or otherwise? Perhaps its your child's birthday and its time to cut and divide the cake in a way that none of the children gets sad by his/her share?

Overwatch sounds like a game I shouldn't want to play: a hero-focused team shooter that seems aimed at players given to godlike acts of ballistic skill. But I should know better. This is Blizzard we're talking about, after all, a studio that turned a generic fantasy-verse born from a niche real-time strategy game into a global online roleplaying sensation. After chatting with Overwatch co-director Jeffrey Kaplan, I'm almost convinced it's a game for me--the sort of lapsed, Quake-era clanner who has lost interest in competitive shooters. Here, by way of our lightly edited conversation, is a rundown of why.

The fear of the Earth being struck by an enormous asteroid has been the source for many science fiction films, but the threat of mankind being wiped out by an impact may be lower than we think. Until now, scientists used the strength of rocks found on Earth to model the damage these giant space boulders would cause. But researchers have now sacrificed a rare sample of meteorites to test the physical properties of asteroids and found they crumbled more easily than expected. It is an idea popular in science fiction, but the threat of mankind being wiped out by asteroids (artist's impression pictured) might be a lot lower than you think. Even though space rocks fall to Earth as meteorites all the time, very few are recovered.

LAGOS--Nigeria is beating the West at its own word game, using a strategy that sounds like Scrabble sacrilege. By relentlessly studying short words, this country of 500 languages has risen to dominate English's top lexical contest. Last November, for the final of Scrabble's 32-round World Championship in Australia, Nigeria's winningest wordsmith, Wellington Jighere, defeated Britain's Lewis Mackay, in a victory that led morning news broadcasts in his homeland half a world away. It was the crowning achievement for a nation that boasts more top-200 Scrabble players than any other country, including the U.K., Nigeria's former colonizer and one of the board game's legacy powers. "In other countries they see it as a game," said Mr. Jighere, now a borderline celebrity and talent scout for one of the world's few government-backed national programs.

U.S. special operations forces launched an airstrike Saturday against Taliban leader Mullah Akhtar Mohammad Mansour in a remote town in Pakistan, U.S. military officials said, and initial evidence suggested Mansour was killed. U.S. military and intelligence officers were still assessing the results of the strike by multiple armed drones, they cautioned. The operation, which was authorized by President Obama and took place around 3 p.m. local time (3 a.m. Pacific time), hit Mansour as he traveled in a vehicle with another man along the Pakistan-Afghanistan border, southwest of the town of Ahmad Wal. Mansour has emerged as the leader of a resurgent Taliban that in recent months has mounted a powerful insurgency against the Afghan government in a string of attacks that have killed civilians, Afghan forces and U.S. military personnel.

By rights, Yuval Noah Harari should be an anonymous academic buried in an obscure university department somewhere toiling away on his somewhat dusty discipline – medieval military history. He's a professor of history at the Hebrew University of Jerusalem and there is almost nothing in his background to suggest that he would write a book that has become one of the most talked about non-fiction bestsellers of the year – Sapiens. Or that he'd join the globetrotting TED-ocracy: the academic superstars who travel the world delivering keynotes on zeitgeisty topics, in Harari's case, the not inconsiderable subject of the history of the whole of mankind. When I meet him, he's just been the star turn at Penguin Random House's global sales conference. In May, he packed out Hay. Earlier this month, he delivered a TED talk.
