I feel that's one of the central questions of fantasy. What did we lose when we entered the 20th and 21st century, and how can we mourn what we lost, and what can we replace it with? We're still asking those questions in an urgent way.
The line between outside and inside is fuzzier in fantasy. Maybe that's something people are looking for.
I'm a fantasy writer. I don't do SF. This is important to me. If you're not clear on what genre you're in, everything gets muddled, and it's hard to know which rules you're breaking.
