A mindclone is a software version of your mind. He or she is all of your thoughts, recollections, feelings, beliefs, attitudes and values, and is experiencing reality from the standpoint of whatever machine their mindware is running on. Mindclones are mindfiles being used and updated by mindware that has been set to be a functionally equivalent replica of one’s mind. A mindclone is your software-based alter ego, doppelganger, or mental twin. If your body died, but you had a mindclone, you would not feel that you personally died, although the body would be missed more sorely than amputees miss their limbs.
We have absolutely no experience with mindclones. Never in history has there been anything like them. Hence, it is natural to find it difficult to understand the concept. From time immemorial we have thought of our identity as being limited to one instantiation, namely that contained within our body. To grasp mindcloning it is necessary to envision identity as being a unique pattern of thinking that can occur in two or more substrates or forms. If you can accept that a mind can be duplicated, with appropriate mindware and a rich enough mindfile, then you have accepted that a single identity can occur at least twice.
Creepy, isn’t it? There is more here.
