Is it time to put the brakes on the development of artificial intelligence (AI)? If you’ve quietly asked yourself that question, you’re not alone. In the past week, a host of AI luminaries signed an open letter calling for a six-month pause on the development of more powerful models than GPT-4; European researchers called for tighter AI regulations; and long-time AI researcher and critic Eliezer Yudkowsky demanded a complete shutdown of AI development in the pages of TIME magazine. Meanwhile, the industry shows no sign of slowing down. In March, a senior AI executive at Microsoft reportedly spoke of “very, very high” pressure from chief executive Satya Nadella to…

If all goes to plan, sometime in November 2024, NASA’s newly announced Artemis II crew – Christina Koch, Victor Glover, Reid Wiseman and Canadian astronaut Jeremy Hansen – will cram themselves into their Orion space capsule and begin their final checks for launch. As they sit perched atop the gargantuan Space Launch System (SLS) rocket at Kennedy Space Center in Florida, waiting for the inferno beneath them to light, the world will hold its breath. Should they survive the violence of that ignition and the journey into Earth orbit, an adventure the likes of which we haven’t seen in more than half a century will await…

New telescopes with unprecedented sensitivity and resolution are being unveiled around the world – and beyond. Among them are the Giant Magellan Telescope under construction in Chile, and the James Webb Space Telescope, which is parked a million and a half kilometres out in space. This means there is a wealth of data available to scientists that simply wasn’t there before. The raw data off just a single observation from the MeerKAT radio telescope in South Africa’s Northern Cape province can measure a terabyte. That’s enough to fill a laptop computer’s hard drive. MeerKAT is an array of 64 large antenna dishes. It uses radio signals from…

Schools and universities are panicking about artificial intelligence (AI) and cheating. But AI presents far more significant threats to equity in education. Fears of cheating typically arise from concerns about fairness. How is it fair that one student spends weeks labouring over an essay, while another asks ChatGPT to write the same thing in just a few minutes? Fretting about giving each student a “fair go” is essential to maintaining the idea of New Zealand as an egalitarian country.

In American writer Mark Twain’s autobiography, he quotes — or perhaps misquotes — former British Prime Minister Benjamin Disraeli as saying: “There are three kinds of lies: lies, damned lies, and statistics.” In a marvellous leap forward, artificial intelligence combines all three in a tidy little package. ChatGPT, and other generative AI chatbots like it, are trained on vast datasets from across the internet to produce the statistically most likely response to a prompt. Its answers are not based on any understanding of what makes something funny, meaningful or accurate, but rather, the phrasing, spelling, grammar and even style of other webpages. It…

Last week, artificial intelligence pioneers and experts urged major AI labs to immediately pause the training of AI systems more powerful than GPT-4 for at least six months. An open letter penned by the Future of Life Institute cautioned that AI systems with “human-competitive intelligence” could become a major threat to humanity. Among the risks, the possibility of AI outsmarting humans, rendering us obsolete, and taking control of civilisation. The letter emphasises the need to develop a comprehensive set of protocols to govern the development and deployment of AI. It states: These protocols should ensure that systems adhering to them are safe beyond a reasonable…

A recent open letter by computer scientists and tech industry leaders calling for a six-month ban on artificial intelligence development has received widespread attention online. Even Canada’s Innovation Minister François-Philippe Champagne has responded to the letter on Twitter. The letter, published by the non-profit Future of Life Institute, has asked for all AI labs to stop training AI systems more powerful than GPT-4, the model behind ChatGPT. The letter argues that AI has been “locked in an out-of-control race to develop and deploy ever more powerful digital minds that no one — not even their creators — can understand, predict, or reliably control.” The letter…

In architecture, new materials rarely emerge. For centuries, wood, masonry and concrete formed the basis for most structures on Earth. In the 1880s, the adoption of the steel frame changed architecture forever. Steel allowed architects to design taller buildings with larger windows, giving rise to the skyscrapers that define city skylines today. Since the industrial revolution, construction materials have been largely confined to a range of mass-produced elements. From steel beams to plywood panels, this standardized kit of parts has informed the design and construction of buildings for over 150 years. That may soon change with advances in what’s called “large-scale…

With the launch of ChatGPT to the public, post-secondary institutions are aware of the seismic impact this could have on both the business and art of education. Educators’ emotions have ranged from intrigue and excitement to panic about massive disruption. Public access to this large language model (LLM) raises important questions about teaching and learning, including the design of meaningful assessments, the appropriate use of technology, maintaining academic integrity and quality control over education. There are also broader existential, ethical and equity concerns, such as those raised by AI ethics researcher Timnit Gebru, computational linguist Emily M. Bender and others. In response to these legitimate concerns, there…

As a victim or suspect of a crime, or witness to an offence, you may find your actions, behaviour and character scrutinised by the police or a barrister using CCTV footage. You may assume all the relevant footage has been gathered and viewed. You may sit on a jury and be expected to evaluate CCTV footage to help determine whether you find a defendant guilty or innocent. You may believe you will see all the key images. You may trust the camera never lies. However, the evidence we gathered during our study of British murder investigations and trials reveals how, like other…
