The first sentence I saw when following the link:

"Before “offering solutions,” sci-fi must actually grapple with the material realities of our present"

makes me think that the author has never read any SF or perhaps has only seen recent mass market blockbuster entertainment on video. An enormous amount of SF uses the 'permission' that the genre affords to focus closely and discard irrelevant detail precisely in order to 'grapple with the material realities of our present'.

You can see this as far back as Jules Verne in 20 000 Leagues under the Sea and most likely much earlier. How about Accelerando by Charles Stross for something more recent. What about Brunner's Shockwave Rider, Karel Capek's RUR, Light Of Other Days by Baxter and Clarke. All dealing with real social issues amplified and illuminated by SF.

I, and many others, could go on at seriously boring length on this subject
