Artificial intelligence brings new dangers to society that must be addressed "head on", the prime minister will warn on Thursday, as the government admitted it could not rule out the technology posing an existential threat. Rishi Sunak will refer to the "new opportunities" for economic growth offered by powerful AI systems but will also acknowledge they bring "new dangers" including risks of increased cybercrime, disinformation and upheaval to jobs. In a speech delivered as the UK government prepares to host global politicians, tech executives and experts at an AI safety summit in Bletchley Park next week, Sunak is expected to call for honesty about the risks posed by the technology. "The responsible thing for me to do is to address those fears head on, giving you the peace of mind that we will keep you safe, while making sure you and your children have all the opportunities for a better future that AI can bring," Sunak will say. "Doing the right thing, not the easy thing, means being honest with people about the risks from these technologies."

Break-ups are something that many people dread - especially when you don't see them coming. Now, a new study has revealed a key way to tell if your partner is thinking of breaking up with you, based on their language. The study found that people contemplating the end of a relationship change their launguage and start saying'I' and'we' more. According to the experts, the use of the word'I' is correlated with depression and sadness, and is a key sign that someone is carrying a heavy cognitive load. The researchers hope the findings will provide people with a key insight into how loved ones may respond over time to the end of a romantic relationship.

Artificial intelligence (AI) is no longer the stuff of science fiction. AI determines what news you get served up on the internet. It plays a key role in online matchmaking, which is now the way most romantic couples get together. It will tell you how to get to your next meeting, and what time to leave home so you're not late. AI often appears both omniscient and neutral, but on closer inspection we find AI learns from and adopts human biases.

The technology behind the First Industrial Revolution was water and steam power, which mechanized textile production. The innovation made factories commonplace, which brought more people to cities and caused social upheaval. In the second, electric power made mass production possible. The third was based on semiconductors, which facilitated the data processing that automated production and spawned the digital age. Now a fourth industrial revolution is taking shape. The technology behind it is the internet of things--networks of connected devices such as sensors, robots, and wearables.

If there's anything that can be said for 2020, it's a year of upheaval turning everything we know on its head. This is true for the public relations industry as much as anything. While the tides of change have been swirling for a while now, it's more evident than ever that we're on the cusp of a major reckoning in how we do our jobs – and the tools we use to do them. There have been noble and creative attempts at introducing technology into the PR workflow for decades, mostly static media databases, stylized measurement dashboards, endless monitoring tools, influencer databases and social media management platforms. But uptake has been slow and performance uneven.

Cognizant of a technological sea change underway in the private and public sectors, and accelerated by COVID-19, Microsoft hosted a virtual summit June 23 on artificial intelligence. Eight guests included five experts from the tech company as well as the research firm CCS Insight, The Kroger Co. and Snohomish County, Wash., which recently used AI to create chatbots to disseminate critical information. Microsoft U.S. Chief Digital Officer Jacky Wright started the event by talking about why AI is becoming so important for large organizations. She said it comes down to the power of data, for two broad purposes: to accumulate and share new knowledge, and to solve problems. She polled an audience of industry officials about the top barriers to their AI adoption strategies, and the No. 1 answer was "defining the AI strategy."

In its first issue of 2010, the scientific journal Nature looked forward to a dazzling decade of progress. By 2020, experimental devices connected to the internet would deduce our search queries by directly monitoring our brain signals. Crops would exist that doubled their biomass in three hours. Humanity would be well on the way to ending its dependency on fossil fuels. It warned that all these advances could be derailed by mounting political instability, which was due to peak in the US and western Europe around 2020. Human societies go through predictable periods of growth, the letter explained, during which the population increases and prosperity rises. Then come equally predictable periods of decline. In recent decades, the letter went on, a number of worrying social indicators – such as wealth inequality and public debt – had started to climb in western nations, indicating that these societies were approaching a period of upheaval. The letter-writer would go on to predict that the turmoil in the US in 2020 would be less severe than the American civil war, but worse than the violence of the late 1960s and early 70s, when the murder rate spiked, civil rights and anti-Vietnam war protests intensified and domestic terrorists carried out thousands of bombings across the country. The author of this stark warning was not a historian, but a biologist.

To describe the future of work, Richard Baldwin is developing a new lexicon. The professor of international economics at the Graduate Institute in Geneva warns that we are unprepared for the ways in which new technology is changing the nature of globalization. Baldwin's new book, The Globotics Upheaval: Globalization, Robotics, and the Future of Work, is a natural follow-up to his 2016 book, The Great Convergence. Three years ago, he explained how a third wave of globalization--a collapse in the cost of the movement of people thanks to technology--would be the most disruptive, because it hits workers in the service sector. Baldwin's new book, published earlier this year, breaks down what this disruption will entail.

For a while, it seemed that Universal Basic Income might be the magic solution to the predicted imminent destruction of all our jobs. Great leaps forward in robotics and artificial intelligence are already threatening widespread human redundancy, with the first largescale cull looming for anyone who drives for a living. Companies from General Motors to Google offshoot Waymo are racing to be the first to flood the roads with completely autonomous cars. In Dubai – a city rapidly emerging as a pacemaker for technological change – the emirate's Autonomous Transportation Strategy envisages that a quarter of all journeys in the city will be automated by 2030. Transportation upheaval is just the beginning of the disruption threatened by the so-called Fourth Industrial Revolution. The world is already experiencing what economists call "job polarization."

The revolutionary development in artificial intelligence and machine learning, and its dramatic consequences, is a global economic upheaval and one that will both provide opportunities for and challenge India dramatically. Discussing India's response to this global upheaval, Martin Wolf, associate editor and chief economics commentator, Financial Times, London, said, "India needs to devote careful thought to the domestic implications of the revolution in artificial intelligence." He explained, "As a country with a growing population and labour force and huge employment in services, the implications might be very radical, both creating and destroying opportunities on a massive scale." Wolf, who delivered the seventh NCAER CD Deshmukh Memorial Lecture 2019 in New Delhi on Tuesday, spoke on the theme of Challenges for India from the Global Economic Upheavals. The other upheavals he addressed were the rapid economic rise of Asia, the strategic rivalry between the US and China, growing protectionism in the US and the associated erosion of the liberal global economic order and the threat of climate change. Wolf, who has many times described India as a "premature superpower", summed up his arguments, saying that all these global upheavals will have profound implications for India as "they alter the environment in which it [India] hopes to develop, they demand substantial and far-sighted domestic responses and they will force it to clarify its global stance."
