I think I disagree. To me, good science fiction proposes some future technology, then explores what the ramifications are for society and/or individuals. It is relevant to us now, because it explores how our lives would be different if something new was introduced.

A great example is a short story by Asimov about someone who creates a television that can look into the past. The government in the story has known for a long time that such a thing was possible, but kept it secret because of a simple unintended consequence: the elimination of personal privacy. If you can look into the arbitrary past, then you can look into anyone's past of 5 seconds ago. The consequences are society-shifting.
