“Minds are software states... Software doesn't have identity. Software in some sense is a physical law. ...The maintenance of the identity is not terminal. It's instrumental to something else. You maintain your identity so you can serve your meaning. So you can do the things that you are supposed to do before you die. ...For most people the fear of death is the fear of dying before they are done with the things that they feel they have to do even though they cannot quite put their finger on... what that is.”
