=== Mind transfer ===
''Main - [[Problems with mind uploading]]''

In the universe of Altered Carbon, there is wide spread acceptance that one's consciousness exists unambigiously within the special 'stack' implant devices. Implanted at age 1, it doesn't appear to be a [[Ghost in the Shell]] level brain-replacement [[cyberbrain]]. Most likely it features a copy of memory and personality and a consciousness bridge combined, effectively allowing a consciousness to 'be' an organic brain and the stack at the same time.

Assuming continuity of consciousness within the stack itself, there are a number of other unanswered questions:
* How is continuity of consciousness maintained during long distance 'needlecast' network transfers?
* Consciousness copying is heavily government regulated to prevent duplication of consciousnesses via 'multi sleeving'. It is suggested that this technological restriction is circumvented by the rich, e.g. Miriam Bancroft's multi-sleeve sex party island. It's unclear the nature of financial barrier that prevents this happening far more often such in in the case of multi-sleeving gangster featured.
* Whilst neo-catholics are against [[digital resurrection|resurrection]] aka 're-sleeving', it is unclear if they also object to re-sleeving a living person or otherwise transferring consciousness via needlecasting.

The alien origin of the stack technology is alluded to but is left mostly unexplored so far.
