I think, that BOT's have the right of beeing. If you, as a software developer, are able to create a bot that is able to clasify content that it is likeable by other users, why not let them be? Anyway, there is a much bigger problem: If both authors and curators were BOTs and they would represent the mayority of the user base., they will be up-voiting their own computer generated content (only likeable by the algorithms) and therefore the BOT community would get higher SP than the human community. The BOTs will take over, first, steemit, and second the world.
