That post is so rich with time horizons. It articulates almost exactly what FLG believes is the end goal of Marxim and the modern left.
To be completely honest, the post is somewhat frightening. Look, FLG likes economic and technological progress as much as anybody. He likes when humanity can produce more goods and services that are useful, relevant, and meaningful to people using fewer resources. But the idea that if material necessity disappeared that there'd be a utopia is dangerously naive.
