Back at the dawn of AI, artificial general intelligence was conceived as the ability to “make machines use language, form abstractions and concepts, solve kinds of problems now reserved for humans, and improve themselves.” Half a century on, we’re still nowhere near making an AI with the multitasking abilities of a human—or even an insect. AGI has become one of the most divisive ideas in AI. But the goalposts of the search for AGI constantly shift. And even if we do build an AGI, we may not even realize we’ve done so. How do we make an AGI? AI is incredibly good at achieving particular goals in particular environments, from games to protein folding. The tricky part comes next: yoking multiple abilities together. Moving from one-algorithm to one-brain is one of the biggest open challenges in AI. Deep learning is the most general approach we have, but some researchers say we shouldn’t fixate too much on it, instead combining multiple techniques and approaches to achieve AGI. Why is AGI controversial? Part of the reason nobody knows how to build an AGI is that few agree on what it is. Without evidence on either side about whether AGI is achievable or not, the issue becomes a matter of faith. Why does it matter? A few decades ago, when AI failed to live up to the hype, funding disappeared and researchers moved on. It took many years for the technology to emerge from what were known as “AI winters” and reassert itself. That hype, though, is still there. And while it’s needed to get investors and policymakers excited, unrealistic expectations can infect decision-making, leading people to ignore very real problems—such as the way racial bias can get encoded into AI by skewed training data, the lack of transparency about how algorithms work, or questions of who is liable when an AI makes a bad decision—in favor of more fantastical concerns about things like a robot takeover.

But up to now, superconductors have had to be cooled to extremely low temperatures, which has restricted them to use as a niche technology. Now, researchers say they’ve made a breakthrough, achieving room-temperature superconductivity in a compound containing hydrogen, sulfur, and carbon at temperatures as high as 58 °F (13.3 °C). The previous record had been 8 °F.  Like the previous records, the new record was attained under extremely high pressures—roughly two and a half million times greater than that of the air we breathe. Woah there: Superconductors could change our world, but they still need to be cooled to low temperatures in order to work. This makes them more complicated, expensive, and prone to failure. It remains to be seen whether scientists can devise stable compounds that are superconducting not only at ambient temperature, but also at ambient pressure.

And for good reason: “Bennu is a time capsule,” says Thomas Zurbuchen, the head of NASA’s Science Mission Directorate. “It has been out there for 4.5 billion years, and carries the history of that environment with it.”  If we study Bennu and other asteroids like it in deep detail, we can potentially unravel how the ingredients that lead to the formation of planets like Earth—and, eventually, life—come together. Now comes the hard bit: getting a sample. That’s precisely the goal come October 20, when OSIRIS-REx will plunge down toward the surface of the asteroid and attempt to scoop up some rubble and dust from the surface. It will be one of the hardest things NASA has ever attempted, taking place over a fraught 4.5 hours more than 200 million miles away from Earth. And then it has to bring the sample safely back over the course of the next three years. There are more than a few ways things can go wrong. Read the full story.  —Neel V.

So what can you do with that many zeros of compute? Exascale supercomputers will perform a quintillion calculations every second (that’s a billion billion, or 1,000,000,000,000,000,000). To put that number in perspective, you would need every single person on Earth calculating 24 hours a day for more than four years to do what an exascale supercomputer can do in one second. With exascale supercomputers, scientists and researchers will be able to make clean energy advancements, eliminate diseases, develop more efficient vehicles, mitigate climate change, and more. This Sunday—October 18—is Exascale Day, when we celebrate the scientists, researchers and engineers using supercomputing and computational science to change the world for the better. Learn how exascale supercomputers will help take on many of the world’s biggest challenges.
