The day will come when it will be possible to create a brain-machine interface using nano sized devices at hundreds or even millions of locations in the brain and spinal cord.
At that point a form of human immortality will be achieved as a disembodied brain will have I/O with the world without the sense organs of the body.
The uses that such I/O could be put to are mind-boggling.
Keeping a brain alive and well in an artificial environment could actually be done today, but what use would it be without I/O?
I/O
I/O
So off to work I go.
Immortality in a Virtual reality matrix along with thousands of others..
In a Peter Watts novel it’s called “Heaven”
In a Black Mirror episode it’s copying ones consciousness and uploading it into a VR cloud with many others.
“Keeping a brain alive and well in an artificial environment could actually be done today, but what use would it be without I/O?”
There isn’t even a cure for dementia. What makes you think the brain can be healthily preserved today without a body?
