This chapter examines mind uploading, in which one allegedly thwarts death by “uploading” oneself to a computer. This chapter examines various possible ontologies which might be associated with “uploaded” persons: the non-self view; the view that they would be immaterial souls; the view that they would be computers, or particular physical parts of computers; the view that they would be patterns; the view that they would be simulated objects. Various problems with each proposal are identified. An additional problem is discussed: regardless of which personal ontology is true with respect to us now (pre-upload), it seems doubtful that one could be moved into a computer by way of the processes which would be involved in mind uploading (e.g., copying one’s mental states to a computer). Finally, practical matters are considered, chief among them being the question of whether one should attempt to “upload” oneself if given the opportunity.
