In his 2019 State of the Nation address, South Africa’s President Cyril Ramaphosa announced that he was creating a commission on the fourth industrial revolution (4IR). The term refers to the integration of advanced digital technologies like AI and robotics, as well as automation, into various economic and social domains. The first (1760s to early 1800s), second (1870s to early 1900s) and third (1950s to late 20th century) industrial revolutions were mechanical and electronic in nature. The 4IR is characterised by the fusion of physical, digital and biological systems. It is fundamentally reshaping industries, work and societies. Ramaphosa acknowledged at…

Online platforms have become popular meeting places for people looking to find intimate partners, making them a prime target for cybercriminals. Online romance fraud has become a global phenomenon. According to the Federal Bureau of Investigation in the US, romance scams accounted for losses to about 24,000 Americans, exceeding US$1 billion, in 2022. On the African continent, Nigeria and Ghana have emerged as hubs for internet fraud. The “Yahoo Boys” operating in Nigeria and “Sakawa Boys” in Ghana have a reputation for engaging in various fraudulent schemes, including online romance…

American president Donald Trump has issued an executive order to withdraw aid from South Africa. He was reacting to what he has called the South African government’s plan to “seize ethnic minority Afrikaners’ agricultural property without compensation”. Afrikaners are an ethnic and linguistic community of white South Africans whose home language is Afrikaans. Trump’s outrage is based on a misinterpretation of a new law – the Expropriation Act which came into effect in January 2025. Trump’s action, amplified by provocative comments from billionaire Elon Musk, has reignited debate about the concept of “white victimhood”. We asked Nicky Falkof, who has…

The practice of medicine has undergone an incredible, albeit incomplete, transformation over the past 50 years, moving steadily from a field informed primarily by expert opinion and the anecdotal experience of individual clinicians toward a formal scientific discipline. The advent of evidence-based medicine meant clinicians identified the most effective treatment options for their patients based on quality evaluations of the latest research. Now, precision medicine is enabling providers to use a patient’s individual genetic, environmental and clinical information to further personalize their care. The potential benefits of precision medicine also come with new challenges. Importantly, the amount and complexity of…

Imagine attending a funeral where the person who has died speaks directly to you, answering your questions and sharing memories. This happened at the funeral of Marina Smith, a Holocaust educator who died in 2022. Thanks to an AI technology company called StoryFile, Smith seemed to interact naturally with her family and friends. The system used prerecorded answers combined with artificial intelligence to create a realistic, interactive experience. This wasn’t just a video; it was something closer to a real conversation, giving people a new way to feel connected to a loved one after they’re gone. Virtual life after death…

Meta has announced it will abandon its fact-checking program, starting in the United States. It was aimed at preventing the spread of online lies among more than 3 billion people who use Meta’s social media platforms, including Facebook, Instagram and Threads. In a video, the company’s chief, Mark Zuckerberg, said fact checking had led to “too much censorship”. He added it was time for Meta “to get back to our roots around free expression”, especially following the recent presidential election in the US. Zuckerberg characterised it as a “cultural tipping point, towards once again prioritising speech”. Instead of relying on…

Around the world, cards and apps are the default way to pay – but nowhere is the transition away from cash more obvious than in Sweden. The Bank of Sweden notes that the amount of cash in circulation in the country has halved since 2007. Part of this is due to a unique Swedish law that prioritises “freedom of contract” above any legal requirement to accept cash. In other words, it is up to businesses – including banks – whether they take cash. Public transport, stores and services typically do not accept cash as payment, and there is no infrastructure…

About one-third of the global population, around 3 billion people, don’t have access to the internet or have poor connections because of infrastructure limitations, economic disparities and geographic isolation. Today’s satellites and ground-based networks leave communications gaps where, because of geography, setting up traditional ground-based communications equipment would be too expensive. High-altitude platform stations – telecommunications equipment positioned high in the air, on uncrewed balloons, airships, gliders and airplanes – could increase social and economic equality by filling internet connectivity gaps in ground and satellite coverage. This could allow more people to participate fully in the digital age. One of…

For more than a decade, researchers and journalists have relied on a digital tool called CrowdTangle to track and fight the spread of viral falsehoods online. But earlier this week, the owner of CrowdTangle, Meta, shut the tool down. The tech giant has replaced it with its new Content Library, which it says will serve the same purpose and be “more user friendly”. As long-time users of CrowdTangle to track and analyse online misinformation campaigns, we are sceptical of this claim. We are also very concerned by the fact CrowdTangle’s closure comes at a time when misinformation on social media…
