The document discusses blue brain technology, which aims to create a virtual brain known as the "blue brain" that could function similarly to a human brain. It would allow uploading contents of the natural brain into it to preserve intelligence, knowledge, and skills even after death. This would be accomplished through nanobots that scan the brain's structure and activity and interface it with a computer system. While this technology could allow remembering things without effort and using intelligence after death, it also presents disadvantages like becoming dependent on computers and others potentially misusing technical knowledge.
