  • Rethink... the promise of AI

    In 2023, ChatGPT took Artificial Intelligence into the mainstream. Now there's a bewildering choice of human-like chatbots to choose from. Generative AIs can produce pictures and video from a text prompt, and many websites and apps are now labelled "Powered by AI".

    This new technology can do lots of things and tech companies have raised vast amounts of money from investors based on its potential.

    But what is AI actually for?

    Certain specialised AIs have a clear purpose. AlphaFold2 can predict how proteins fold-up and won its creators the Nobel Prize for Chemistry, and Google Translate is an AI with a purpose that’s clear from its name.

    But so far there is no must-have or "killer" application for the Large Language Models and Generative AIs.

    The future of AI is equally hazy. Will AI somehow lead to all-purpose "Artificial General Intelligence", autonomous robots or even machine consciousness? Or is this all just the stuff of fantasy and nightmares?

  • Rethink... regeneration

    The government has launched the Pride in Place scheme but is it possible to regenerate urban areas without leaving local people out?

    Most buildings have a certain shelf life before they need renovating. Social norms change and the ways people interact develop as society transforms with time. And local economies can change dramatically with once prosperous industrial areas falling silent, or tourist hot spots left behind by low-cost air travel.

    But is it possible to do this without being accused of gentrification? Swanky new buildings are introduced attracting people with money, house prices go up, expensive shops and cafes open up and before you know it, local people are priced out of the area.
    So are there ways to improve urban areas without leaving local residents behind? How much should any regeneration project acknowledge and honour local history? Isn’t attracting new people, with new ideas and new businesses a vital part of any regeneration project?

  • Rethink...middle age

    People are living longer and delaying life's milestone moments. How does this affect our middle years and should we be paying more attention to people in this phase of their lives?

    For some, middle age can be a very challenging period in their lives. Today, people are postponing the milestones in life that traditionally signified a change in priorities. People are having children later in life meaning parents in their 40s or even 50s are looking after small children. Jobs for life no longer exist and housing is so expensive that many have no choice but to pay costly rents.

    All of these phenomena have given rise to the so called “sandwich Generation” – simultaneously looking after children but also elderly parents. Many experience multiple roles- worker, parent, carer, spouse and friend – and juggling the demands of all of those roles can lead to burnout.
    Academic literature on happiness has until recently suggested that our satisfaction with life as we age is hump shaped. When we're young, we're happy — and then that declines, bottoming out in middle age. As we pass middle age and get older, we get happier again. But is that still the case? Is mid-life a uniquely unhappy place to be?

  • Rethink... nightlife

    The Night Times Industries Association says one in four venues have shut down since 2020, and the sector will face an irreversible decline unless the government provides urgent support.

    The industry was one of the worst hit during the pandemic, and it's asking for cuts to National Insurance, a permanent cut in VAT and a reform of business rates to help it keep afloat.

    The NTIA claims the night time economy contributes more than £153 billion to the UK economy and supports over 2 million jobs.

    Culturally, the sector punches above its weight. The nightclub boom in the last 50 years gave us disco, acid house, drum and bass and grime, as well as many other sub-genres of music. But nightclubs are expensive and consumers are finding their thrills elsewhere; drink is cheaper from supermarkets, and why search for someone you fancy on the dancefloor when you can use a dating app?

    And as nightclubs struggle, so do small music venues, where artists like Ed Sheeran, Dua Lipa, Coldplay, Arctic Monkeys Blur and Oasis started out, as well as many others.

    People are willing to pay hundreds of pounds to see those same artists in giant venues like Co-op Live in Manchester or at Wembley Stadium, so what can be done to make sure the next wave of new artists have somewhere to play? Should the government intervene? Should big venues subsidise smaller ones, or is it up to fans to throw them a lifeline?

    Or has nightlife in its current form - much like variety music halls - taken its last curtain call?

  • Rethink... winners and losers

    Do you agree with either of these statements?

    Illegal migrants come here and are a burden on services and the taxpayer.

    OR
    The only way to reduce inequality is to tax billionaires and giant companies who avoid tax.

    They may seem on opposite poles of the political spectrum, but both anti-migrant campaigners and anti-capitalists share an identical mindset. Both are demonstrating zero-sum thinking; the belief that if one group wins, another has to lose.

    In itself, zero-sum thinking isn't moral or immoral, right or wrong. But Economists claim it leads to poor economic policy, and they say evidence shows it is possible to create win-win situations for everyone.

    But many of the main parties at Westminster also use zero-sum thinking in their political rhetoric - from Reform and the Greens, to the Conservatives and Labour. Also, the first past the post electoral system is literally a zero-sum process. So is this kind of thinking baked-into UK politics?

    So are there particular groups of people that are more prone to zero-sum beliefs? Where did this mindset come from? What economic conditions encourage zero-sum thinking, and how deeply are these beliefs held?

  • Rethink: should we stop flying?

    Aviation is far more difficult to decarbonise than other sectors of the economy, because kerosene is the perfect fuel for planes. It produces enough power to enable planes to fly, yet it is light enough for them to get off the ground and cross the world.

    Alternatives are thin on the ground; batteries are too heavy, clean hydrogen power is in its infancy, while Sustainable Aviation Fuel - or SAF - is expensive and in short supply. Although the Government has a "SAF-mandate", only 22% of all jet fuel supplied by 2040 will have to be sustainable.

    New airliners are more fuel-efficient than ever before, and both routes and air-traffic control are being optimised. But if growth outpaces efficiencies, greenhouse gas emissions will continue to rise.

    And passenger demand is back at pre-pandemic levels. In 2024 the UK was the third largest market in the world for flights.

    In the absence of any immediate solution, should we fly less, if at all? How realistic and affordable are slower alternatives like the train? Could passengers be penalised for taking more than one return flight a year? And should the Government rather than individuals be taking responsibility for change?

  • Rethink: how can flying be less polluting?

    Aviation has a problem: it's reliant on fossil fuels which release greenhouse gases when they're burned in a jet engine. Other industries are worse polluters, but in the next few decades, they are likely to decarbonise much faster than the airline sector.

    Why? Because kerosene is a light enough fuel for planes to get off the ground, while producing enough thrust for them to do so. Also it enables airliners to carry passengers to the other side of the world.

    International flight has only been around for less than 100 years, but research suggests that it's responsible for 4% of total global warming to date. It's not just that airliners pump out carbon dioxide, but they also emit nitrous oxides and soot. Even contrails, which are mostly water vapour, have a warming effect high up in the atmosphere.

    Can efficiencies in jet engines, optimal routes and air traffic control lead to less fuel being used? What technologies are available to make flying cleaner? Is the pace of change fast enough to meet net zero by 2050?

  • Rethink...the meaning of terrorism

    What is terrorism?

    Without doubt, it is a pejorative term; few people would ever want to be called a terrorist, and when the word terrorism is attached to a belief system, it delegitimises it in the eyes of the public.

    It's an emotive word with severe consequences for any individual or group given the label. Virtually everybody agrees that being a terrorist is not a good thing and that the law must seriously punish them.

    But there isn't an agreed international definition of what terrorism is.

    The UK has a legal definition, but it differs from other western democracies. When does property damage become a terror offence? How do police officers decide the difference between support for a cause and membership of a proscribed organisation? Should individuals without an ideology who plan or commit mass murders be considered terrorists? Are UK anti-terror laws too broad, or too narrow? And can violence by states be counted as terrorism?

  • Rethink... summer holidays

    Two weeks in the sun - it's the classic summer getaway. For many of us, summer holidays are something to look forward to all year.

    But some of the most popular destinations for British holidaymakers are under strain. Protesters in Barcelona and Majorca have been pushing back at the number of visitors they host - even spraying them with water pistols. Locals are unhappy at being priced out of the housing market and feeling pressure on public services - but they also need tourists to support their economies.

    At the same time, many destinations are experiencing increasingly hot summers, with sometimes catastrophic results. Two years ago, 20,000 tourists in Rhodes were forced to evacuate their hotels to get away from wildfires. Climate models suggest future summers will be hotter still.

    So is it time to rethink how we approach the summer holiday?

    Should we be considering different destinations for our holidays - swapping Mediterranean beaches for northern Europe or British destinations? Would those places be ready for more summer visitors? How can tourist destinations change to meet shifting demands? Is it time for schools to move away from the long summer break?

    We'll look at the history of the beach holiday, and try and imagine what summer holidays will look like in the future. And we'll ask - what is a summer holiday for?

  • Rethink... the UK's relationship with China

    President Trump promised "America First" on the campaign trail, and has delivered that in his second term, unleashing a trade war and causing global economic instability.

    Although China and the USA have recently agreed a temporary truce in the trade war, the US President regards Beijing as an economic enemy. Perversely, Donald Trump's actions may push other countries into China’s embrace.

    For some countries, like Russia, that's a natural fit. Others, like China’s neighbours South Korea and Japan, have agreed to talks about a free-trade agreement, while the EU says it is seeking to "engage constructively" with Beijing.

    So where does that leave the UK? Of late, Labour ministers have been on a charm offensive, with the Chancellor, the Foreign Secretary and the Energy Secretary all visiting China, as well as a recent trade delegation.

    So should the UK be seeking closer ties with China? What are the risks, and is China even interested in us?
