Grand Narratives as Moe Elements

I have recently been reading through Azuma Hiroki’s Otaku: Japan’s Database Animals. In it, he puts forth the theory that a database has replaced the Grand Narratives of modernity. He’s dealing with a lot of theory on postmodernity that has a long history of discourse by other philosophers and theorists, but he sums up the basic ideas quite succinctly:

[In modernity] Various systems were consolidated for the purpose of organizing members of society into a unified whole: this movement was a precondition for the management of society. These systems became expressed, for instance, intellectually as the ideas of humanity and reason, politically as the nation-state and revolutionary ideologies, and economically as the primacy of production. Grand narrative is a general term for these systems… Modernity was ruled by the grand narrative. In contrast, in postmodernity the grand narratives break down and the cohesion of the social entirety rapidly weakens. (p.26)
