I've been re-reading lots of sci fi recently. PKD and Willam Gibson, my favorites.
Think about the boon to the world it is that Philip K. Dick was mad. He gave America its own Kafka/Borges/prophet. He helped change the expectations of a genre. He reinvented paranoia as an aesthetic sublime. And he wrote 16 novels in 2 years!
I'm crushing the dementia beneath the pavement with my bare hands.
