The idea of the self escaping bodily death by transforming into an age-proof, sickness-proof essence that can be uploaded into a computer or network dates back at least to Vernor Vinge’s 1981 novella True Names. A year after that, William Gibson gave us the word cyberspace to describe a new place where humans might exist, potentially forever, outside the physical world.
Basically beyond our digital footprint lies our immortal cybersoul, and the "self" you create online won’t die when you do. Now there are businesses , known as a digital estate management service, that provide a safe, secure repository for your online property that lets you grant access to digital assets for friends and loved ones in the event of loss, death, or disability. Apparently it's an idea who's time has come.
