It's Wednesday 21st October 2015 - the exact date traveled forward to in the time-travelling blockbuster Back To The Future II. We speak to futurist Glen Hiemstra about the technology the film got right and wrong. We also speak to Greg and Jill Henderson from Arxpax - inventors of a real-life hoverboard. And Kentaro Toyama, author of a book called Geek Heresy, tells us why technology may not always be the answer.
