Christopher Nolan, the film director, has said that he is not interested in new technology and has “rewarded” cinemas that still use celluloid by allowing them advanced access to his new film, Interstellar. Cinemas that have long discarded the traditional methods of showing films will have to wait several days to screen the movie. Alongside this distrust for new film technology, Nolan does not use a mobile phone or have an email address. We would like to know if there are any methods of technology that you ignore. Do you steadfastly refuse to have Wi-Fi at home or hate the thought of a smartphone? Do you balk at computers and prefer to write everything by hand? Tell us which modern electronics you would never consider using.
