That was basically what everyone agreed the future would look like in the 1960s. :) In fact I seem to remember reading somewhere that Kubrick was inspired by this terminal, but I can't find that now, so my mind may have made that up.
I don't know if Kubrick ever traveled through the terminal since he apparently had a serious fear of flying. It seems likely that some of the people involved with the production of 2001 would have, though. And it would have been brand new at the time.
