Mmm. Maybe, but... the thing is, all the stuff you describe still involves a setting that is more technologically and (in some ways) socially advanced than we are right now. We can't make jets that fly in space, 1960s-looking or otherwise. Or construct giant city-smashing robots. It would require materiel sciences that are well beyond state of the art and are, in effect, magical.
And once you're operating on that plane you can construct all sorts of justifications for the aesthetics. "We build giant robots because our gyroscopic and stabilizing technology are such that that particular form factor offers massive maneuverability advantages over a classic tank form in an urban environment" and suchly.
The point is, that stuff is all still head-and-shoulders above what we have right now. It's not like you have, say, Destroid squadrons that have to communicate with each other using signal flags rather than highly encrypted burst transmissions. Sometimes it seems like people in UF are walking around with less everyday tech on them than I am right now in 2014 (or at least, using it less well) and on occasion that's bothered me.
