Adam Roberts, back in 2014:

There is, I think, a genuine human fascination with outer space. Apollo could have capitalised upon that fascination and expanded into broader and better conceived programmes. But it didn’t, and the real reason it didn’t is that people found a more satisfying way scratch their metaphorical itch. Like a diet of sweets and pastries instead of spinach and brown rice, big screen sci-fi quelled our appetite for space travel in a way both delicious and fundamentally unhealthy. Why should people around the globe give up a significant fraction of their respective gross national products to pay for actual space travel when Hollywood could give them all the thrills of outer space in virtual form?

I think this point — which I missed back when it was published — harmonizes nicely with the argument I made in my essay from the same year, “Fantasy and the Buffered Self”:  

Fantasy — in books, films, television shows, and indeed in all imaginable media — is an instrument by which the late modern self strives to avail itself of the unpredictable excitements of the porous self while retaining its protective buffers. Fantasy, in most of its recent forms, may best be understood as a technologically enabled, and therefore safe, simulacrum of the pre-modern porous self. 

Stories as distractions, as substitute satisfactions, as soma.
