Whether you are talking about the disempowerment we or some of us already experience, or are more on the page of thinking about some future cataclysm, I think I'm generally with you here. "History does not walk on its head," and all that.
The GRRM quote is an interesting choice here though. It implies that what is most important is dynamic. First Joffrey et al, now bread. But one could go even farther in this line: ideas, ideology, and, in GoT's case, those who peddle them can only ever form ideas within their context. Philosopher's are no more than fancy pundits, telling people what they want to here, or even sustaining a structural status quo that is otherwise not in their control. In a funny paradoxical way, there are certainly a lot of philosophers who would agree with something like this picture.
And just honestly, yes, maybe killing god is killing the philosopher too. I don't think Nietzsche would disagree at least...
