Eternal life could be achieved through brain uploading

According to Dr. Hannah Critchlow, a neuroscientist at Cambridge University, people could live forever through converting their brain into software.

In essence, this would allow us to “live inside a machine” – something similar to what we have seen in sci-fi movies. However, it could be feasible only as soon as a computer capable of supporting 100 trillion circuit connections is created.

Dr. Critchlow made this statement at the Hay Festival which took place the previous week in Wales. Speaking of the way the human brain works, she compared it to a complex circuit board.

“We are about 100 billion nerve cells and the most complicated circuit board you could imagine,” she said.

This comparison has to do with the fact that the processes occurring in the brain involve an enormous amount of neural connections, just like a computer’s work is based on electric circuits.

“If you had a computer that could make those 100 trillion circuit connections – then that circuit is what makes us,” Dr. Critchlow said.

The neuroscientist also spoke of the common myths about the human brain, and, in particular, the 10 percent one. It’s not that we only use 10 percent of our brain capacity, she said, it’s that most of the time, our brains are running in idle mode in order to save energy.

In fact, despite taking up only 2% of the body’s mass, the human brain consumes about 20% of all energy! That’s why not all areas of the brain are active all the time – most of them are "powered" only when being used.
