With the headlines like that, it's usually safe to assume the latter. I remember reading in Popular Science on and off for years (00s) about all kinds of innovations that were right around the corner ('10-15 or so), much of which still remains firmly in "maybe one day" stage. Maybe a bunch of things didn't come to pass that I don't remember, but I clearly remember a lot of articles about air travel (delta wings everywhere!) and commercial space travel (Burt Rutan!). For a sense of how low my expectations got, I remember reading about the Boeing 7E7 and being surprised when a new generation of airliners was in fact coming out. That experience has been born out many times since, in my adult life. I've all but completely stopped following "science journalism" as a result. I'll hear about it when it actually happens.
