While the idea that we could upload our brains to a computer is pretty terrifying, it's not confined to science fiction.
That's according to Professor Brian Cox, who told The Sun Online that he found "no reason at all why you cannot simulate human intelligence".
You might have heard the phrase artificial intelligence bandied about by Apple or Google, whose clever computing methods power smart assistant Siri and a massive search engine that learns how to become better at their jobs.
But these are a series of processes that appear similar to intelligence, not to be confused with "mind uploading" like that dodgy Johnny Depp flick, Transcendence.
What many future-gazers, eminent scientists and the likes of Elon Musk are hoping for is a true symbiosis between the biological and digital world.
