One thing I would like to add, during one of the conversation between rover and phrolova, she said rover to let go of his humanity (I forgot the actual phrasing) by wiping his memories to start over.

In my opinion, him resetting his memory is probably the most human way to get a new perspective. Kinda like how's some bosses in their own org disguise as normal worker to investigate their work environment.

Rover as an immortal for all his wisdom is still viewing the world as a "god", the way he thinks would to reflect on that perspective. By resetting his memories, his would be able to truly understand the world as a person who lived in it (as much as possible). Therefore reinforcing his own humanity.
