Altered Carbon is an American science fiction web television series created by Laeta Kalogridis and based on the 2002 novel of the same title by English author Richard K. Morgan. In a world where consciousness can be transferred to different bodies, Takeshi Kovacs, a former soldier turned investigator, must solve a murder. The first season consists of ten episodes and premiered on Netflix on February 2, 2018. On July 27, 2018, the series was renewed for a second season of eight episodes. The series received generally positive reviews.
The series takes place over 360 years in the future, with most episodes set in the year 2384, in a futuristic metropolis known as Bay City. In the future, a person's memories and consciousness can be decanted in a disk-shaped device called a cortical stack, which is implanted in the vertebrae at the back of the neck. These storage devices are of alien design and have been reverse engineered and mass produced. Physical human or synthetic bodies are called "sleeves" and stacks can be transferred to new bodies after death, but a person can still be killed if their stack is destroyed. While this theoretically means anyone can live forever, only the wealthiest, known as "Meths" in reference to Methuselah, have the means to do so through clones and remote storage of their consciousness in satellites.
