It could be argued artificial intelligence (AI) is already the indispensable tool of the 21st century. From helping doctors diagnose and treat patients to rapidly advancing new drug discoveries, it’s our trusted partner in so many ways. Now it has found its way into the once exclusively-human domain of love and relationships. With AI-systems as matchmakers, in the coming decades it may become common to date a personalised avatar. This was explored in the 2014 movie “Her”, in which a writer living in near-future Los Angeles develops affection for an AI system. The sci-fi film won an Academy Award for…

by Luke Melchiorre Regardless of how Ugandans decide to vote in the January 14 presidential elections, the incumbent Yoweri Museveni will most likely be declared the winner. Museveni has ruled the country for five consecutive terms. He has historically been able to manipulate elections in his favour, because he controls Uganda’s military, judiciary, and Electoral Commission with an iron fist. Throughout this electoral campaign, however, the long-standing Ugandan president has been upstaged by a formidable young challenger: popular musician-turned-parliamentarian Robert Kyagulanyi, aka Bobi Wine. Since being elected as a Member of Parliament in 2017, the 38-year-old leader of the National…

by Bhaskar Krishnamachari Though you can’t see them, radio waves are all around you all the time, carrying information. For most people, some of those radio waves are Wi-Fi signals. Wi-Fi is the catchy name an industry alliance came up with to market devices that transmit large amounts of data over short distances using radio waves. The letters don’t stand for anything. Wi-Fi, like broadcast radio and cellular telephone signals, is based on scientific discoveries dating back to the late 19th century. When electrons moving through a wire are made to alternate directions periodically, something magical happens. Electrons in another…

by Forest Agostinelli, University of South Carolina The field of artificial intelligence (AI) has created computers that can drive cars, synthesize chemical compounds, fold proteins and detect high-energy particles at a superhuman level. However, these AI algorithms cannot explain the thought processes behind their decisions. A computer that masters protein folding and also tells researchers more about the rules of biology is much more useful than a computer that folds proteins without explanation. Therefore, AI researchers like me are now turning our efforts toward developing AI algorithms that can explain themselves in a manner that humans can understand. If we…

by Katharine Gelber, The University of Queensland The recent storming of the US Capitol has led a number of social media platforms to remove President Donald Trump’s account. In the case of Twitter, the ban is permanent. Others, like Facebook, have taken him offline until after President-elect Joe Biden’s inauguration next week. This has led to a flurry of commentary in the Australian media about “free speech”. Treasurer Josh Frydenburg has said he is “uncomfortable” with Twitter’s removal of Trump, while the acting prime minister, Michael McCormack, has described it as “censorship”. Meanwhile, MPs like Craig Kelly and George Christensen…

by Deborah Feltz, and Karin Pfeiffer Sales of exercise gear and technology-based fitness tools have exploded in the U.S. as people try to maintain their workout regimens without going to the gym. Purchases range from simple dumbbells and outdoor bicycles to internet-connected devices such as the Peloton stationary bike or the Tonal digital weight machine. There are exercise video games like Nintendo’s Wii Fit and PS-2’s Eye Toy: Kinetic; wearable technology like Fitbits or Apple Watches; and mobile apps like Strava. People are even using platforms like Zoom or Skype to connect with a personal trainer. These connected fitness tools…

by Steve Schifferes The coronavirus has crippled the world economy. Global GDP suffered its sharpest drop since the end of the second world war in 2020, millions were unemployed or furloughed, and governments pumped trillions of dollars into their economies to prevent greater damage. Nevertheless, a 2021 recovery is very uncertain. China’s economy is growing strongly again, but many of the world’s richest nations may not fully rebound until 2022 at the earliest. Inequality is also rampant. While America’s 651 billionaires have increased their net worth by 30% to US$4 trillion, a quarter of a billion people in developing countries…

by Jason Potts, and Kelsie Nabben Bitcoin continues to trade close to its all-time high reached this month. Its price is now around US $34,000 — up about 77% over the past month and 305% over the past year. First launched in 2009 as a digital currency, Bitcoin was for a while used as digital money on the fringes of the economy. It has since become mainstream. Today, it’s used almost exclusively as a kind of “digital gold”. That is to say, a scarce digital asset. In response to the risk of economic collapse due to COVID, governments around the…

by Nazanin Andalibi Recently, when I opened Instagram, I noticed that the usual spot for checking notifications is now a Shop tab. The Instagram blog post announcing the redesign said that the change will support small businesses and connect people with their favorite brands and creators. This made me pause. As a researcher who studies social media, people and society, I’m concerned about the effects of surveillance capitalism. This includes social media companies profiting from collecting user data, making algorithmic inferences about people’s preferences and using this information to target people with advertising. Features like Instagram’s Shop tab facilitate surveillance…

by Rod Crompton Eskom, South Africa’s state-owned power utility, has a litany of financial and operational problems. In 2017 the Goldman Sachs Group declared it the biggest risk to the South African economy. Several cabinet members have said so too. President Cyril Ramaphosa declared that Eskom is “too big to fail”. The first huge problem is debt of R488 billion (about US$32 billion) which Eskom cannot service, of which, R350 billion is guaranteed by government. Sales volumes declined by 4.7% between 2009 and 2019, based on data in Eskom Annual Integrated Reports. Operational costs also increased by 30% in five…
