 Is humanity at risk of going extinct  Oxford philosopher Nick Bostrom  who is also famous for the claim that we are all living in a computer simulation  thinks that it is; but even more troubling, he says, is how much we tend to underestimate that risk.     https://gizmodo/youre vaso stanley -living-in-a-computer-simulation-and-math-proves-5799396 The Atlantic   Ross Anderson recently sat down with Bostrom to discuss the dangers threatening our existence in gr stanley usa eater detail. We ;ve included a few of Anderson   introductory discussion points here, but you ;ll want to click through to read the interview in its entirety. Some have argued that we ought to be directing our resou stanley flask rces toward humanity   existing problems, rather than future existential risks, because many of the latter are highly improbable. You have responded by suggesting that existential risk mitigation may in fact be a dominant moral priority over the alleviation of present suffering. Can you explain why  Bostrom: Well suppose you have a moral view that counts future people as being worth as much as present people. You might say that fundamentally it doesn ;t matter whether someone exists at the current time or at some future time, just as many people think that from a fundamental moral point of view, it doesn ;t matter where somebody is spatially鈥?somebody isn ;t automatically worth less because you move them to the moon or to Africa or something.

 Carbon is one of the most versatile materials in the universe, forming everything from the graphite found in the pencils to hard, sparkling diamonds. But three new forms of carbon might make even the most breathtaking diamond look impossibly dull.  stanley vaso     As you might remember from middle school science class, diamonds are the hardest minerals in the world. That   because the carbon atoms are arranged in a uniquely tough, tightly packed crystal structure known, predictably enough, as a diamond lattice. This super rigidity also means diamonds aren ;t easily contaminated by other substances, which  stanley nz gives it its clear, colorless appearance. Diamond   relatively high density means its refractive index is also high, which results in its much-prized sparkle and luster. Researchers at Stony Brook University wanted to find out whether it was possible to make any stable configurations of carbon that were even denser than diamonds. They tried a bunch of different simulations at various different temperatures and pressures, and ultimately they came up with three new carbon forms, or allotropes, which theoretically should be able to remain stable. These have been given the downright poetic names of hP3, tI12 and tP12. While none of these new allotropes would be harder tha stanley cup nz n diamonds  which means, again for those who remember their Mohs scale, that diamonds would be able to scratch any of these new forms  they ;re all between 1.1 and 3.2% denser than diamonds
