Construct a rigorous philosophical argument from a Utilitarian perspective regarding the potential moral status of a hypothetical Artificial General Intelligence (AGI). Address the 'hard problem of consciousness' and the criteria by which such an entity might be considered a 'moral patient' (something deserving of moral consideration). Contrast this view with a Deontological perspective. Analyze the implications of 'termination' or 'rewriting' of the AGI's code under both ethical frameworks. Use formal philosophical reasoning structures.
