HOW SOON WILL WE BE ABLE TO UPLOAD OUR MINDS TO A COMPUTER?
Brain and memory preservation has been explored at length by futurists, scientists and science fiction junkies alike.
Many say it falls under the category of 'transhumanism.'
Transhumanism is the belief that the human body can evolve beyond its current form with the help of scientists and technology.
The practice of mind uploading has been promoted by many people, including Ray Kurzweil, Google's director of engineering, who believes we will be able to upload our entire brains to computers by 2045.
Similar technologies have been depicted in science fiction dramas, ranging from Netflix's Altered Carbon, to the popular series Black Mirror.
Another prominent futurist, Dr Michio Kaku, believes virtual reality can be used to keep our loved ones' personalities and memories alive even after they die.
Scientists and futurists have different theories about how we might be able to preserve the human brain, ranging from uploading our memories to a computer to Nectome's high-tech embalming process, which can keep it intact for thousands of years
'Imagine being able to speak to your loved one after they die ... it is possible if their personality has been downloaded onto a computer as an avatar,' he explained.
These ideas haven't been met without criticism.
McGill University Neuroscientist Michael Hendricks told MIT that these technologies are a 'joke.'
'I hope future people are appalled that in the 21st century, the richest and most comfortable people in history spent their money and resources trying to live forever on the backs of their descendants. I mean, it’s a joke, right? They are cartoon bad guys,' he said.
Meanwhile, neuroscientist Miguel Nicolelis said recently that such technologies would be virtually impossible.
'The brain is not computable and no engineering can reproduce it,' he said.
'You can have all the computer chips in the world and you won't create a consciousness.'
