This article by science fiction writer Neal Stephenson focuses on how science fiction has/can/should influence and drive innovation in America.
Stephenson is one of those science fiction writers who has been able to expand beyond just genre readers and become respected by what you might call the critical establishment. Caveat lector – he’s on my list, but I have never read him. But, it appears as if he’s on a level with a writer like China Miéville, though perhaps not up to Margaret Atwood heights.
Much of it is a cri de couer regarding the failure of the current age to follow up on the dreams of a previous age, but I mostly wanted to point how two ways, mentioned in the article, that sci fi can push scientific achievment.
