If freezing your severed head is part of your plan to live forever, then Danila Medvedev is one of the few people on the planet who may be able to help you. In 2005, he founded KrioRus, a cryonics company, and has also worked as Vice-President of the Science for Life Extension Foundation, based in Moscow. Bringing back the deceased, or as Medvedev prefers to call them, ‘the temporarily dead’ is only one of many things the founder of the Russian Transhumanist Movement is passionate about. Aside from life extension, we had a fascinating chat about Douglas Engelbart’s unfulfilled vision for interfaces, the Incan system of multidimensional record keeping, the Russian Cosmism movement and what went wrong with the nanotech revolution.
