"Honestly, I think the barriers are imaginary, the walls have already been breached and the key to literature in the early 21st century is one of confluence. There’s not much high and low culture any more: there’s just mingling streams of art and what matters is whether it’s good art or bad art. But then, I come from comics, and miss the days when it was a gutter art-form in which nobody was expected to make art; and think that SF was much more vibrant and relevant before they taught it in universities."
Neil Gaiman in The New Yorker’s Ask the Author. As Robin Sloan says, the most interesting part is the “confluence” of art in the 21st century: the breaking down of barriers between high and low.
