I think I finally understand why we don't see alien civilization is space and what the great filter is.
It's simple, they've realized that existence is a meaningless venture and doesn't lead anywhere regardless of how advanced their civilization gets, so they simply just self-terminate.

What's the point of existing anyway? It doesn't lead anywhere, it doesn't really do anything. We just progress technologically and our species ends up where ultimately? A super intelligent AI species that can traverse the cosmos and conquer all galaxies until the heat death of the universe? Then what? We escape to a parallel reality and continue doing the same thing? To what end?

Reality is meaningless and the only rational course of action is to go extinct.
