That’s according to Nottingham Trent ethics and philosophy lecturer Benjamin Curtis who made the comments in light of controversial experiments on pig brains.
Last month, Yale University announced it had successfully resurrected the brains of more than 100 slaughtered pigs and kept them alive for up to 36 hours.
Scientists said it could pave the way for brain transplants and may one day allow humans to become immortal by hooking up our minds to artificial systems after our natural bodies have perished.

‘Even if your conscious brain were kept alive after your body had died, you would have to spend the foreseeable future as a disembodied brain in a bucket, locked away inside your own mind without access to the sense that allow us to experience and interact with the world,’ Curtis told The Conversation.
‘In the best case scenario you would be spending your life with only your own thoughts for company.
‘Some have argued that even with a fully functional body, immortality would be tedious. With absolutely no contact to external reality it might just be a living hell.
‘To end up a disembodied human brain may well be to suffer a fate worse than death.’
The pig research was presented at a National Institutes of Health meeting by Yale University neuroscientist Nenad Sestan
Researchers were able to successfully remove the heads of between 100 and 200 pigs and resuscitate their brains while detached from the body.
The organs were connected to a closed-loop system the scientists dubbed ‘BrainEX’ that pumped key areas with artificial oxygen-rich blood to sustain life.
In what Dr Sestan described as a ‘mind-boggling’ and ‘unexpected’ result, billions of cells in the brains were found to be alive and healthy.
He told the NIH it is possible the brains could be kept alive indefinitely and that additional steps could be taken to restore awareness, according to a report in the Massachusetts Institute of Technology’s Technology Review.
The neuroscientist said his team chose not to attempt either because ‘this is uncharted territory.’
The brains of pigs survived for up to 36 hours after the animals had been decapitated. The results could one day lead to human brains that can live outside the body, a long fascination of science fiction – including the 1983 film ‘The Man With Two Brains’ (pictured)
Chemicals added to prevent swelling during the procedure would likely prohibit consciousness indefinitely.
This means it may not be possible for the team to resuscitate brains that can still ‘think’ using their current methods.
According to Dr Sesta, the brains they operated on were definitely not alive or conscious.
‘That animal brain is not aware of anything, I am very confident of that,’ he said, according to the MIT report.
Previous research has shown it is possible to keep the brains of a number of mammals alive after the organ is removed from the body.
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
