SF in Trouble

This is from an interview with Ted Chiang, though this quote comes from Gavin Grant:

"Science fiction is one of the biggest threads in popular entertainment," Grant says. "There are lots of big movies, lots of TV shows based on science fiction premises, but science fiction is having this real trouble looking into the future and imagining what will happen. To look a decade or a hundred years in the future is very difficult, and there are a couple of outs that writers have been using. One, they say it's too difficult to look into the future so we don't have to, we can just write fantasy. Or they just look in the past and write steampunk and things like that. Don't get me wrong, I like these things, but I think one of the things Ted does is to extrapolate rigorously and somewhat harshly, in a way that people can recognize from the life they're living."

The quote interests me, because it answers part of my question, where is SF going? What has been happening in the field? It's a better answer than the one I gave in the previous post.
