Start the Week - The Future of Capitalism

Anne McElvoy talks to the social theorist Jeremy Rifkin who foresees the gradual decline of capitalism and the rise of a collaborative economy. As new technology enables greater sharing of goods and services, Rifkin argues that it provides a challenge to the market economy. The sociologist Saskia Sassen warns that the majority of people may not enjoy the fruits of this new world as increasing inequality, land evictions and complex financial systems lead to their expulsion from the economy. The Conservative MP Kwasi Kwarteng looks back at the history of international finance and how gold and war have shaped the economic order of today.

More or Less: Behind the Stats - Killed for being female?

Are 100 million women missing from the world? A listener asks More or Less to explore this powerful statement - "More girls were killed in the last 50 years, precisely because they were girls, than men killed in all the wars in the 20th century." The quote is from a book called 'Half the Sky' by Nicholas D. Kristof and Sheryl WuDunn. It has been used in articles, by UN agencies and on TV to highlight the fatal consequences of discrimination of women based on their sex. But is it true? More or Less looks at the evidence. How can we know if a woman is killed precisely because she is a woman? And how do we know how many men have been killed in war?

TLDR - #23 – A Bitcoin Story for People Who Don’t Care About Bitcoin

When Wired reporter Andy Greenberg read Newsweek's cover story claiming to have found mysterious Bitcoin creator Satoshi Nakamoto, he was disappointed. Not so much that the mystery had been solved, but that the answer to the search was not all that interesting. But then, as the Newsweek started getting picked apart, he got a tip about another possible Bitcoin creator: a very ill, very brilliant cryptographer named Hal Finney. 

Andy Greenberg is the author of This Machine Kills Secrets: How WikiLeakers, Cypherpunks, and Hacktivists Aim to Free the World's Information.

Anne McElvoy looks back at the life of the maverick scientist James Lovelock who pioneered the theory of Gaia, of a self-regulating Earth. Lovelock also looks to the future and the next evolution of Gaia which could lead to the extinction of human life, and a rise of Artificial Intelligence, but the writer and ecologist George Monbiot prefers his future world with wolves, wild boars and beavers living alongside humans. The UN's intergovernmental panel on climate change has warned to expect more volatile weather patterns, and the physicist Joanna Haigh explains how scientists from all disciplines are working together to measure the impact of solar activity on the Earth's climate.

More or Less: Behind the Stats - Magic Numbers

Do you have a favourite number - one you love, one you think stands out from all the others? Author Alex Bellos joins us to talk about his quest to find the world's favourite number and discuss whether numbers really can be magical, mystical and memorable, or whether it's all mumbo jumbo. Why are odd numbers so appealing? Which number strikes fear into some people's hearts? And why do lists of questions like these always come in threes? This programme was first broadcast on the BBC World Service.
