Well, apart from its technical definition, a mindclone is (1) an example of the sort of religion created by worshipers of technology and (2) more evidence of our society’s prevalent mind/body dualism:
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. . . .
