In Ghost in the Shell (1995), there appears to be 3 intelligent forms
- Type 1: a completely organic person. Example: section 9's chief
- Type 2: a brain from a type 1 + some codes + a bio-mechanical body; the first 2 terms of the sum constitute the "ghost" part whereas the body constitutes the "shell" part. Example: Major
- Type 3: an AI program that isn't tied down to a physical humanoid body. Example: the Puppet Master
Question: why does the Puppet Master (a Type 3) want to merge with the ghost of a Type 2 so that it can share the shell with the ghost?
The movie explains something about the desire to reproduce and to die but it's not clear to me. In what senses can a type 2 reproduce or die and how does this satisfy the need of the Puppet Master? Perhaps my categorizing of intelligence into 3 forms above is completely wrong so please correct me on that as well if you so choose.
