That metric's likely to be biased in favour of information & communication technologies, because fiction disproportionately relies on characters having limited information.
It relies on them having many deficiencies. If information deficiency is a common trope of fiction, that slant also indicates that a technology with solves it is that much more significant.
It's certainly evidence, but it's evidence based on fiction, which favours the sensational, dramatic, and unusual. One way for a TV drama or action film to advance its plot is to have a character get shot. This is far more popular than advancing the plot by having a character spend too long manually washing clothes with a scrub board. But I don't infer that bulletproof vests are a more significant technology than the washing machine! Just that shooting someone's more cinematic than scrubbing clothes.
SIAI benefactor and VC Peter Thiel has an excellent article at National Review about the stagnating progress of science and technology, which he attributes to poorly-grounded political opposition, widespread scientific illiteracy, and overspecialized, insular scientific fields. He warns that this stagnation will undermine the growth that past policies have relied on.
