Wow.
I see the story of Groundhog Day as a "monkey" who was unhappy with his life growing up to become a man who had learned to love his life and the people that were a part of it.
The original "monkey" would never have survived those 10,000 years, and in fact didn't. Only the man had survived.
Anyway, there's not much more to say. It's clear that we have two very different views of human nature. I see human potential as something great, especially if one has the time for actualization.
A lesser man might fail, but I don't think that Phil had grown into a lesser man. He had learned to love other people, to love himself, and to love his life in general. He had become a "great souled" person. Perhaps he would feel set apart from others, but I don't see that holding him back because he still loves those others.
