Jaron Lanier has a fair claim to be the man who made virtual reality possible. He and some friends created the first avatars in their garage, and he has been involved in developing tools that allow us to simulate surgery, and computers to recognise human faces. But he is now having doubts about the direction technology is taking us in, and has just written a book voicing his concerns called Who Owns The Future?.

Then, Jo Fidgen meets an Australian boatman at the Kumbh Mela festival in India. Andrew Turner has built himself a boat and is now ferrying pilgrims - for free - at Sangam, the confluence of the Ganges and Yamuna rivers, where the world's largest religious ceremony is held.
