Could the future see the emergence and adoption of a new field of engineering called nucleonics, in which the energy of nuclear fusion is accessed at relatively low temperatures, producing abundant clean safe energy? This kind of idea has been discussed since 1989, when the claims of cold fusion first received media attention. It is often assumed that the field quickly reached a dead-end, and that the only scientists who continue to study it are cranks. However, as we’ll hear in this episode, there may be good reasons to keep an open mind about a number of anomalous but promising results.

Our guest is Jonah Messinger, who is a Winton Scholar and Ph.D. student at the Cavendish Laboratory of Physics at the University of Cambridge. Jonah is also a Research Affiliate at MIT, a Senior Energy Analyst at the Breakthrough Institute, and previously he was a Visiting Scientist and ThinkSwiss Scholar at ETH Zürich. His work has appeared in research journals, on the John Oliver show, and in publications of Columbia University. He earned his Master’s in Energy and Bachelor’s in Physics from the University of Illinois at Urbana-Champaign, where he was named to its Senior 100 Honorary.

This episode of London Futurists Podcast is a special joint production with the AI and You podcast which is hosted by Peter Scott. It features a three-way discussion, between Peter, Calum, and David, on the future of AI, with particular focus on AI agents, AI safety, and AI boycotts.

Peter Scott is a futurist, speaker, and technology expert helping people master technological disruption. After receiving a Master’s degree in Computer Science from Cambridge University, he went to California to work for NASA’s Jet Propulsion Laboratory. His weekly podcast, “Artificial Intelligence and You” tackles three questions: What is AI? Why will it affect you? How do you and your business survive and thrive through the AI Revolution?

Peter’s second book, also called “Artificial Intelligence and You,” was released in 2022. Peter works with schools to help them pivot their governance frameworks, curricula, and teaching methods to adapt to and leverage AI.

The guest in this episode is Hugo Spowers. Hugo has led an adventurous life. In the 1970s and 80s he was an active member of the Dangerous Sports Club, which invented bungee jumping, inspired by an initiation ceremony in Vanuatu. Hugo skied down a black run in St.Moritz in formal dress, seated at a grand piano, and he broke his back, neck and hips when he misjudged the length of one of his bungee ropes.

Hugo is a petrol head, and done more than his fair share of car racing. But if he’ll excuse the pun, his driving passion was always the environment, and he is one of the world’s most persistent and dedicated pioneers of hydrogen cars.

He is co-founder and CEO of Riversimple, a 24 year-old pre-revenue startup, which have developed 5 generations of research vehicles. Hydrogen cars are powered by electric motors using electricity generated by fuel cells. Fuel cells are electrolysis in reverse. You put in hydrogen and oxygen, and what you get out is electricity and water.

There is a long-standing debate among energy experts about the role of hydrogen fuel cells in the energy mix, and Hugo is a persuasive advocate. Riversimple’s cars carry modest sized fuel cells complemented by supercapacitors, with motors for each of the four wheels. The cars are made of composites, not steel, because minimising weight is critical for fuel efficiency, pollution, and road safety. The cars are leased rather than sold, which enables a circular business model, involving higher initial investment per car, and no built-in obsolescence. The initial, market entry cars are designed as local run-arounds for households with two cars, which means the fuelling network can be built out gradually. And Hugo also has strong opinions about company governance.

Can we use AI to improve how we handle conflict? Or even to end the worst conflicts that are happening all around us? That’s the subject of the new book of our guest in this episode, Simon Horton. The book has the bold title “The End of Conflict: How AI will end war and help us get on better”.

Simon has a rich background, including being a stand-up comedian and a trapeze artist – which are, perhaps, two useful skills for dealing with acute conflict. He has taught negotiation and conflict resolution for 20 years, across 25 different countries, where his clients have included the British Army, the Saudi Space Agency, and Goldman Sachs. His previous books include “Change their minds” and “The leader’s guide to negotiation”.

Our guest in this episode is Nate Soares, President of the Machine Intelligence Research Institute, or MIRI.

MIRI was founded in 2000 as the Singularity Institute for Artificial Intelligence by Eliezer Yudkowsky, with support from a couple of internet entrepreneurs. Among other things, it ran a series of conferences called the Singularity Summit. In 2012, Peter Diamandis and Ray Kurzweil, acquired the Singularity Summit, including the Singularity brand, and the Institute was renamed as MIRI.

Nate joined MIRI in 2014 after working as a software engineer at Google, and since then he’s been a key figure in the AI safety community. In a blogpost at the time he joined MIRI he observed “I turn my skills towards saving the universe, because apparently nobody ever got around to teaching me modesty.”

MIRI has long had a fairly pessimistic stance on whether AI alignment is possible. In this episode, we’ll explore what drives that view—and whether there is any room for hope.

Our guest in this episode is Henry Shevlin. Henry is the Associate Director of the Leverhulme Centre for the Future of Intelligence at the University of Cambridge, where he also co-directs the Kinds of Intelligence program and oversees educational initiatives. 

He researches the potential for machines to possess consciousness, the ethical ramifications of such developments, and the broader implications for our understanding of intelligence. 

In his 2024 paper, “Consciousness, Machines, and Moral Status,” Henry examines the recent rapid advancements in machine learning and the questions they raise about machine consciousness and moral status. He suggests that public attitudes towards artificial consciousness may change swiftly, as human-AI interactions become increasingly complex and intimate. He also warns that our tendency to anthropomorphise may lead to misplaced trust in and emotional attachment to AIs.

Note: this episode is co-hosted by David and Will Millership, the CEO of a non-profit called Prism (Partnership for Research Into Sentient Machines). Prism is seeded by Conscium, a startup where both Calum and David are involved, and which, among other things, is researching the possibility and implications of machine consciousness. Will and Calum will be releasing a new Prism podcast focusing entirely on Conscious AI, and the first few episodes will be in collaboration with the London Futurists Podcast.

How can a binding international treaty be agreed and put into practice, when many parties are strongly tempted to break the rules of the agreement, for commercial or military advantage, and when cheating may be hard to detect? That’s the dilemma we’ll examine in this episode, concerning possible treaties to govern the development and deployment of advanced AI.

Our guest is Otto Barten, Director of the Existential Risk Observatory, which is based in the Netherlands but operates internationally. In November last year, Time magazine published an article by Otto, advocating what his organisation calls a Conditional AI Safety Treaty. In March this year, these ideas were expanded into a 34-page preprint which we’ll be discussing today, “International Agreements on AI Safety: Review and Recommendations for a Conditional AI Safety Treaty”.

Before co-founding the Existential Risk Observatory in 2021, Otto had roles as a sustainable energy engineer, data scientist, and entrepreneur. He has a BSc in Theoretical Physics from the University of Groningen and an MSc in Sustainable Energy Technology from Delft University of Technology.

In this episode, we return to the subject of existential risks, but with a focus on what actions can be taken to eliminate or reduce these risks.

Our guest is James Norris, who describes himself on his website as an existential safety advocate. The website lists four primary organizations which he leads: the International AI Governance Alliance, Upgradable, the Center for Existential Safety, and Survival Sanctuaries.

Previously, one of James' many successful initiatives was Effective Altruism Global, the international conference series for effective altruists. He also spent some time as the organizer of a kind of sibling organization to London Futurists, namely Bay Area Futurists. He graduated from the University of Texas at Austin with a triple major in psychology, sociology, and philosophy, as well as with minors in too many subjects to mention.

Our subject in this episode may seem grim – it’s the potential extinction of the human species, either from a natural disaster, like a supervolcano or an asteroid, or from our own human activities, such as nuclear weapons, greenhouse gas emissions, engineered biopathogens, misaligned artificial intelligence, or high energy physics experiments causing a cataclysmic rupture in space and time.

These scenarios aren’t pleasant to contemplate, but there’s a school of thought that urges us to take them seriously – to think about the unthinkable, in the phrase coined in 1962 by pioneering futurist Herman Kahn. Over the last couple of decades, few people have been thinking about the unthinkable more carefully and systematically than our guest today, Sean ÓhÉigeartaigh. Sean is the author of a recent summary article from Cambridge University Press that we’ll be discussing, “Extinction of the human species: What could cause it and how likely is it to occur?”

Sean is presently based in Cambridge where he is a Programme Director at the Leverhulme Centre for the Future of Intelligence. Previously he was founding Executive Director of the Centre for the Study of Existential Risk, and before that, he managed research activities at the Future of Humanity Institute in Oxford.

Our guest in this episode, Ramez Naam, is described on his website as “climate tech investor, clean energy advocate, and award-winning author”. But that hardly starts to convey the range of deep knowledge that Ramez brings to a wide variety of fields. It was his 2013 book, “The Infinite Resource: The Power of Ideas on a Finite Planet”, that first alerted David to the breadth of scope of his insight about future possibilities – both good possibilities and bad possibilities. He still vividly remembers its opening words, quoting Charles Dickens from “The Tale of Two Cities”:

Quote: “‘It was the best of times; it was the worst of times’ – the opening line of Charles Dickens’s 1859 masterpiece applies equally well to our present era. We live in unprecedented wealth and comfort, with capabilities undreamt of in previous ages. We live in a world facing unprecedented global risks—risks to our continued prosperity, to our survival, and to the health of our planet itself. We might think of our current situation as ‘A Tale of Two Earths’.” End quote.

12 years after the publication of “The Infinite Resource”, it seems that the Earth has become even better, but also even worse. Where does this leave the power of ideas? Or do we need more than ideas, as ominous storm clouds continue to gather on the horizon?
