a more constructive (?) type of art with grander vision or ability to change and create genres. Something like a Lord of the Rings which birthed fantasy

Building on this, Tolkien wrote about part of his intent to be the creation of a new mythological past. A leftist project would run perpendicular in that it would be, for lack of a better term, prophetic. It would seek to instill a unifying vision of the post-revolution future, whereas Tolkien in creating fantasy was trying to create a new mythical past. In the beginning of the Silmarillion, there is the creation myth. Would the prophesied revolution take a similar role in the tale of the future we are building? The revolutionaries as the Ainur in a structure similar to Judges instead of genesis.

I think you've touched on a really fascinating topic. I'll be checking that pod out, it sounds cool.
