It’s something of a curse to evolve into a highly self-aware species, as now we have to somehow find the motivation to wash the dishes and do our taxes, all the while knowing that we’re going to die. Figures, then, that some people would be open to exploring any means possible of extending life – even if that means not having a body.

In his book, The Future Loves You: How And Why We Should Abolish Death, neuroscientist Dr Ariel Zeleznikow-Johnston explores the very real science of brain preservation, and whether it might one day be possible to upload consciousness. In this discussion, we explore why brain transplants aren’t an option, why all that you are just might be the connectome, and the process of turning tissue to glass that could one day make it possible to resurrect neural activity from a preserved brain.

Join us as we explore all of this and more in this special bumper episode of We Have Questions.
