Ghost in the Shell’s Cyberbrain and External Memory
The universe of Ghost in the Shell (especially the extension by the subsequent movie “Innocence“ and the two seasons of Stand Alone Complex) makes heavy use of the concept of a computerised brain which can be constantly linked to an wireless network of information and communication but also allows for storage of external memory outside of the physical brain.
The franchise is dealing with the question whether or not a human still is a unique body-mind-connected individual when their brain can be taken and transplanted into a different body on various levels. Expanding on the definition of what makes a human being themselves.
Sharing external memory, recalling details at any point and linking information with one another would be a great feature to play around with in your own mind. Although the philosophical and ethical implications of being able to manipulate information and therefore a person (GiTS “Ghost hacking“) might be a price too high to pay for this convenience.
Black mirrors “The Entire History of You“ (Series 1 Ep. 3) opens another set of questions on recording and even more on obsessing about details in recording and recalling memory.
