Research Fellow Anders Sandberg, at the Future of Humanity Institute at Oxford University, warns Ms Chessen may soon be dealing with larger problems than lost photos and video footage.
He says our hard drives may one day contain the most important digital replacement of all - digitised replicas of our own brains.
Dr Sandberg believes we could be living on hard drives along with our digital possessions in the not too distant future, which would allow us to shed the trouble of owning a body.
The concept is called "mind uploading", and it suggests that when our bodies age and begin to fail like a worn or snapped record, we may be able to continue living consciously inside a computer as our own virtual substitutes.
