by Wally Smith, The University of Melbourne and Greg Wadley, The University of Melbourne Most of us go online multiple times a day. About half of 18–29 year olds surveyed in a 2021 Pew Research Study said they are “almost constantly” connected. How are we to make sense of this significant digital dimension of modern life? Many questions have rightly been asked about its broader consequences for society and the economy. But there remains a simpler question about what motivates people across a range of ages, occupations and cultures to be so absorbed in digital connection. And we can turn…
by Thomas Daum, University of Hohenheim; Frédéric Baudron, International Maize and Wheat Improvement Center (CIMMYT); Ingo Grass, University of Hohenheim; Matin Qaim, University of Bonn, and Regina Birner, University of Hohenheim Cultivating one hectare of maize used to be an arduous task for Precious Banda, a farmer in Zambia. It would take her hundreds of hours to prepare her land before sowing and to keep it weed-free until harvest – equipped with nothing but a small hoe. She says it was backbreaking work: “I can still feel it.” For a few years now she has hired a tractor, and a…
by Nir Eisikovits, UMass Boston The rise of ChatGPT and similar artificial intelligence systems has been accompanied by a sharp increase in anxiety about AI. For the past few months, executives and AI safety researchers have been offering predictions, dubbed “P(doom),” about the probability that AI will bring about a large-scale catastrophe. Worries peaked in May 2023 when the nonprofit research and advocacy organization Center for AI Safety released a one-sentence statement: “Mitigating the risk of extinction from A.I. should be a global priority alongside other societal-scale risks, such as pandemics and nuclear war.” The statement was signed by many…
by Casey Fiesler, University of Colorado Boulder Twitter’s move on July 1, 2023, to limit the number of tweets users can see in a day was the latest in a series of decisions that has spurred millions of users to sign up with alternative microblogging platforms since Elon Musk acquired Twitter last year. In addition to a surge in numbers on Mastodon, the acquisition and subsequent changes boosted small existing platforms like Hive Social and has spawned brand new upstarts like Spoutible and Spill. Most recently the microblogging platform backed by Twitter founder Jack Dorsey, Bluesky, saw a surge of…
by Mohammed Hassan, University of Arizona If you’ve ever wished you had a faster phone, computer or internet connection, you’ve encountered the personal experience of hitting a limit of technology. But there might be help on the way. Over the past several decades, scientists and engineers like me have worked to develop faster transistors, the electronic components underlying modern electronic and digital communications technologies. These efforts have been based on a category of materials called semiconductors that have special electrical properties. Silicon is perhaps the best known example of this type of material. But about a decade ago, scientific efforts…
by David Luke, London School of Economics and Political Science A new European law that imposes the first ever carbon border tax in the world comes into force in October 2023. It will be applied gradually over the next three years before it is fully implemented. A carbon tax is a type of levy imposed on greenhouse gas emissions. It is meant to encourage companies to adopt clean methods of production. But firms could get around the tax by moving production units outside the EU to countries with less strict terms, such as those in Africa, and then exporting products…
by Adrian Barnett, Queensland University of Technology Fraud in science is alarmingly common. Sometimes researchers lie about results and invent data to win funding and prestige. Other times, researchers might pay to stage and publish entirely bogus studies to win an undeserved pay rise – fuelling a “paper mill” industry worth an estimated €1 billion a year. Some of this rubbish can be easily spotted by peer reviewers, but the peer review system has become badly stretched by ever-rising paper numbers. And there’s a new threat, as more sophisticated AI is able to generate plausible scientific data. The latest idea…
by Eric Zeng, Carnegie Mellon University The European Union filed an antitrust case against Google on June 14, 2023, charging that the company abused its power in the online advertising market to disadvantage its competition. The U.S. Department of Justice filed a similar civil antitrust suit against Google on Jan. 24, 2023. The online ad ecosystem is largely built around “programmatic advertising,” a system for placing advertisements from millions of advertisers on millions of websites. The system uses computers to automate bidding by advertisers on available ad spaces, often with transactions occurring faster than would be possible manually. Google runs…
by Brendan H. O’Connor, Arizona State University ChatGPT is a hot topic at my university, where faculty members are deeply concerned about academic integrity, while administrators urge us to “embrace the benefits” of this “new frontier.” It’s a classic example of what my colleague Punya Mishra calls the “doom-hype cycle” around new technologies. Likewise, media coverage of human-AI interaction – whether paranoid or starry-eyed – tends to emphasize its newness. In one sense, it is undeniably new. Interactions with ChatGPT can feel unprecedented, as when a tech journalist couldn’t get a chatbot to stop declaring its love for him. In…
Could organizations use artificial intelligence (AI) language models such as ChatGPT to induce voters to behave in specific ways? Sen. Josh Hawley asked OpenAI CEO Sam Altman this question in a May 16, 2023, U.S. Senate hearing on artificial intelligence. Altman replied that he was indeed concerned that some people might use language models to manipulate, persuade and engage in one-on-one interactions with voters. Altman did not elaborate, but he might have had something like this scenario in mind. Imagine that soon, political technologists develop a machine called Clogger – a political campaign in a black box. Clogger relentlessly pursues…
by Siddhartha Bandyopadhyay, University of Birmingham The recent news that BT would reduce its workforce by as many as 55,000 by 2030, including about 10,000 jobs replaced by artificial intelligence (AI), is part of a growing trend of job losses globally due to various forms of automation. This is borne out by several industry reports, including one from McKinsey Global Institute (MGI) acknowledging that as many as 800 million jobs may be lost globally due to changes in technology by 2030. In our book Work 3.0, the author and business adviser Avik Chanda and I contend that, due to automation…
by Catherine Coveney, Loughborough University and Eric L Hsu, University of South Australia From sleep trackers to wakefulness drugs, the 21st century has seen an influx of new technology that could radically alter the way we sleep. Many of these new technologies chase the dream of optimised slumber. They promise to help tailor our sleep schedules to fit around our social lives, help us sleep for longer or even skip a night’s sleep altogether. Here’s how technology is permeating our sleep, and what the future holds. Time to wake up Sleeping pills have recently been joined by a wave of…
by Nello Cristianini, University of Bath This week a group of well-known and reputable AI researchers signed a statement consisting of 22 words: Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war. As a professor of AI, I am also in favour of reducing any risk, and prepared to work on it personally. But any statement worded in such a way is bound to create alarm, so its authors should probably be more specific and clarify their concerns. As defined by Encyclopedia Britannica, extinction is “the dying…
by Anjana Susarla, Michigan State University Takeaways: A new federal agency to regulate AI sounds helpful but could become unduly influenced by the tech industry. Instead, Congress can legislate accountability. Instead of licensing companies to release advanced AI technologies, the government could license auditors and push for companies to set up institutional review boards. The government hasn’t had great success in curbing technology monopolies, but disclosure requirements and data privacy laws could help check corporate power. OpenAI CEO Sam Altman urged lawmakers to consider regulating AI during his Senate testimony on May 16, 2023. That recommendation raises the question of…
by Anirban Basu, University of Washington Health practitioners are increasingly concerned that because race is a social construct, and the biological mechanisms of how race affects clinical outcomes are often unknown, including race in predictive algorithms for clinical decision-making may worsen inequities. For example, to calculate an estimate of kidney function called the estimated glomerular filtration rate, or eGFR, health care providers use an algorithm based on age, biological sex, race (Black or non-Black) and serum creatinine, a waste product the kidneys release into the blood. A higher eGFR value means better kidney health. These eGFR predictions are used to…
by Gale Sinatra, University of Southern California and Barbara K. Hofer, Middlebury Until very recently, if you wanted to know more about a controversial scientific topic – stem cell research, the safety of nuclear energy, climate change – you probably did a Google search. Presented with multiple sources, you chose what to read, selecting which sites or authorities to trust. Now you have another option: You can pose your question to ChatGPT or another generative artificial intelligence platform and quickly receive a succinct response in paragraph form. ChatGPT does not search the internet the way Google does. Instead, it generates…
by Dennis Hirsch, The Ohio State University and Piers Norris Turner, The Ohio State University The rush to deploy powerful new generative AI technologies, such as ChatGPT, has raised alarms about potential harm and misuse. The law’s glacial response to such threats has prompted demands that the companies developing these technologies implement AI “ethically.” But what, exactly, does that mean? The straightforward answer would be to align a business’s operations with one or more of the dozens of sets of AI ethics principles that governments, multistakeholder groups and academics have produced. But that is easier said than done. We and…
by Milovan Savic, Swinburne University of Technology Montana has made an unprecedented move to become the first US state to ban TikTok. However, doubts have been raised over the decision’s legal foundation, enforcement mechanisms and underlying motives. While the move draws attention to data security on social media, banning TikTok alone may not provide a comprehensive solution to this problem. For one, the move risks alienating the many young people who have come to rely on the app for meaningful connection, and in some cases their income. It also does little in the way of ensuring better future data privacy…
by Pawan Jain, West Virginia University Artificial Intelligence-powered tools, such as ChatGPT, have the potential to revolutionize the efficiency, effectiveness and speed of the work humans do. And this is true in financial markets as much as in sectors like health care, manufacturing and pretty much every other aspect of our lives. I’ve been researching financial markets and algorithmic trading for 14 years. While AI offers lots of benefits, the growing use of these technologies in financial markets also points to potential perils. A look at Wall Street’s past efforts to speed up trading by embracing computers and AI offers…
by Jenny Whilde, University of Florida and Jessica Alice Farrell, University of Florida Human DNA can be sequenced from small amounts of water, sand and air in the environment to potentially extract identifiable information like genetic lineage, gender, and health risks, according to our new research. Every cell of the body contains DNA. Because each person has a unique genetic code, DNA can be used to identify individual people. Typically, medical practitioners and researchers obtain human DNA through direct sampling, such as blood tests, swabs or biopsies. However, all living things, including animals, plants and microbes, constantly shed DNA. The…
by Thapelo Tselapedi, Rhodes University Relations between the People’s Republic of China and Russia on one hand and the west, specifically the US, on the other have become increasingly tense in recent times. For the US, China and Russia represent authoritarian regimes. For China, the US is the source of global insecurity. With a few exceptions like France and the UK, the west sees the presence of Russia and China in the BRICS bloc (which also includes Brazil, India and South Africa) as contaminating the entire bloc as well as their relations with the individual BRICS member countries. This is…
by Alan Christoffels, University of the Western Cape and Sofonias Kifle Tessema Infectious disease outbreaks in African countries are, unfortunately, all too common. Ebola in the Democratic Republic of the Congo or Uganda; Marburg virus in Guinea or Equatorial Guinea; cholera in Malawi; malaria and tuberculosis are among them. These diseases do not respect human-made or porous borders. So it’s essential that scientists in Africa are able to generate and share critical data on the pathogens in time to inform public-health decisions. Genomic sequencing technologies are powerful tools in this kind of work. They enable scientists to decode the genetic…
by Eden Kamar, Hebrew University of Jerusalem and Christian Jordan Howell, University of South Florida There has been a tenfold increase in sexual abuse imagery created with webcams and other recording devices worldwide since 2019, according to the the Internet Watch Foundation. Social media sites and chatrooms are the most common methods used to facilitate contact with kids, and abuse occurs both online and offline. Increasingly, predators are using advances in technology to engage in technology-facilitated sexual abuse. Once having gained access to a child’s webcam, a predator can use it to record, produce and distribute child pornography. We are…
by Chris Impey, University of Arizona The famous first image of a black hole just got two times sharper. A research team used artificial intelligence to dramatically improve upon its first image from 2019, which now shows the black hole at the center of the M87 galaxy as darker and bigger than the first image depicted. I’m an astronomer who studies and has written about cosmology, black holes and exoplanets. Astronomers have been using AI for decades. In fact, in 1990, astronomers from the University of Arizona, where I am a professor, were among the first to use a type…
By Molly Jackson, The Conversation If you’re like me, you’ve spent a lot of time over the past few months trying to figure out what this AI thing is all about. Large-language models, generative AI, algorithmic bias – it’s a lot for the less tech-savvy of us to sort out, trying to make sense of the myriad headlines about artificial intelligence swirling about. But understanding how AI works is just part of the dilemma. As a society, we’re also confronting concerns about its social, psychological and ethical effects. Here we spotlight articles about the deeper questions the AI revolution raises…
