In this episode (which by happenstance is the 100th official episode - although I have released more than that) I chat to Elise Bohan. Elise is a senior research scholar at the Future of Humanity Institute in Oxford University. She has a PhD in macrohistory ("big" history) and has written the first book-length history of the transhumanist movement. She has also, recently, published the book Future Superhuman, which is a guide to transhumanist ideas and arguments. We talk about this book in some detail, and cover some of its more controversial claims.
