In the TV series "Altered Carbon," which is based on the novel of the same name by Richard K. Morgan, the process of duplicating a human mind is known as "stack technology" or simply "stacking."
Here's a brief overview of the process:
Stack: The human mind is digitized and stored in a small device called a "stack." This stack is a data storage unit that contains an individual's consciousness, memories, and identity. The stack is usually implanted in the base of the skull, at the top of the spinal column.
Cortical Stack: The stack is composed of advanced technology that can record a person's entire consciousness and experiences. It's a crucial component of the process and serves as the foundation for duplicating and transferring human minds.
Sleeves: In the world of "Altered Carbon," human bodies are referred to as "sleeves." These sleeves are just temporary vessels, and one's consciousness can be transferred between different sleeves using the cortical stack.
Resleeving: The process of transferring a person's consciousness from one sleeve to another is called "resleeving." This enables individuals to change bodies, essentially achieving immortality as long as their stack remains intact.
Cloning: By duplicating the data from a person's stack, it's possible to create multiple copies of their consciousness. These copies can then be transferred into separate sleeves, effectively creating multiple versions of the same person.
Remote Storage: Besides transferring consciousness between sleeves, individuals can back up their stacks to remote storage facilities known as "Needlecast" or "data banks." This precaution ensures that even if their physical stack is destroyed, their consciousness can be restored into a new sleeve from the most recent backup.
It's essential to note that "Altered Carbon" is a work of science fiction, and the concept of duplicating human consciousness in this manner is purely fictional and speculative. The show explores various ethical, philosophical, and societal implications of such advanced technology.
