I hadn't read that piece, but it's the conclusion I got to after reading a lot of sci-fi in my YA years.
The sci-fi I enjoyed the most would make one impactful change, say allow for intergalactic travel like in The Forever War, or allowing people to backup and restore their brains like in Altered Carbon, and see where that leads.
Others just use sci-fi as a backdrop for an otherwise conventional story, without really engaging with the sci-fi elements. They can be good stories, but I enjoyed the former much more.
There's this quote I heard that said something along the lines of "Good sci-fi uses fictional technology to show us something about human beings that would be difficult to express otherwise".
