Codes and ciphers

The future of ciphers, digital currencies and online banking. With cryptographer Maire O’Neill, philosopher Luciano Floridi and financial journalist Paul Vigna.

And could cryptocurrencies, such as Bitcoin, be the banking revolution which the developing world needs? Bridget Kendall talks to cryptographer Maire O’Neill, philosopher Luciano Floridi and financial journalist Paul Vigna.

Sixty Second Idea to Change the World

Sixty Second Idea to Change the World

Paul Vigna argues that the most important technology in history has been the written word, and education is the most important social good there is. Therefore, he suggests that every operating system in the world, every PC, laptop, tablet, smartphone or whatever, should have a program included with it, which he calls TenBlock, 10 of the world’s most important texts. And because it’s all text, the app wouldn’t take up much space and would bring some of the most important thoughts in human history directly to people.
