As a attendee to an early Sci-fi convention in NYC, after watching “Silent Running” in a theater there, I would have to agree. But not because of the film, but because of what was said. A very good argument was made in one of the speakers talks about the link between science education and sci-fi, that sci-fi actually encourages science in the schools, which at the time, had fallen and was threatened with much fiscal “trimming”. Unrealistically it was thought the root cause of unrest and I would argue the wrong kind of “science” i.e., warfare without representation, the problem, not high school science. So, io9 is right for what I think, very good reasons. Our science fiction writers are often doing just that, encouraging scientific thinking.
