The following question seems interesting: Of the technological advances that have made a substantial difference to the world since the time when science fiction first emerged as a genre, what fraction (weighted by impact, if you like) appeared in science fiction before they became fact, and how closely did the reality resemble the fiction?
Yes. That might actually be a better question—except that the actually-relevant population is presumably something like “technologies introduced in science fiction that seemed like they might actually be possible in the not-outrageously-far future”.

Of course, it’s also important to consider the fraction of technologies introduced in science fiction that then came into existence.
