The Digital Human Folgen

What happens when we abandon a place? And why is it so difficult for us to leave these places behind? In this episode, Aleks explores abandon both on and offline. We tell the story of the only permanent resident of Fukushima's radiation exclusion zone. Naoto Matsura stayed in Tomioka while everyone around him fled. He's now the unofficial caretaker of this abandoned town. Aleks contrasts this with a remarkable example of digital abandon. Meridian 59 was the first massively multiplayer online game. When newer competitors arrived on the scene, many players left. The game has been abandoned and restarted several times over since. Aleks hears from the hardcore community of players who refuse to let the game disappear entirely.

We communicate with each other in more ways than ever and with an ever expanding range of devices and platforms. But they all piggy back on an earlier invention, our original social networking technology - language.In this edition of the Digital Human Aleks Krotoski explores the idea of language as a technology itself and how people over the years have attempted to improve it; re-engineer it for maximum efficiency, or use it as a lever of social change. She speaks to Professor David Crystal about how we're living through a period of rapid language growth comparable to the renaissance or industrial revolution. Evolutionary biologist Mark Pagel explains how we can consider language as a technology devised by natural selection while linguist Arika Okrent charts the attempts down the years by those who think they can perfect the function of language by devising their own.Producer: Peter McManus.

Our brains are still running security software designed to protect us against lions, tigers and bears and we haven't run an update for about 200,000 years. Aleks Krotoski explores how well it works when faced with the risks of the digital world. According David Ropeik author and risk communication expert at Harvard University the modern technological world presents our risk perception abilities with much more complex and abstract problems than it was ever designed to cope with. For him we feel risk rather calculate it so whether its cyber-terrorism or climate change if the risk doesn't immediately push our risk buttons we simply don't know how to react with the risk of getting risk wrong.And no-where can the risks seem more abstract than in the digital world. Aleks explores how we respond to the dangers that lurk there through a range of stories. We spend time being driven round the Channel island of Jersey in the company of Toni an 18 year old who gives lifts to people she's only ever met through Facebook, we'll hear how a professional online poker player uses the minimal information she can glean about other players to know when to bet big and Aleks will also discover how even a walk in the park can put our technology and the private information we keep there in jeopardy.
