A Concerning Trend – Neil Clarke

@clarkesworld I ponder the analogy with photography's impact on painting. As cameras became more common art explored surrealism. I can imagine a future in which my Kindle can compose space opera on the fly with exactly my preferred mix of aliens, mystery, and romance whenever I need escapism, and human-authored stories have gone all House of Leaves or Feersum Endjinn.
@myx @clarkesworld to me this sounds awful 😬
