Trek being about our future is a conceit I've never bought into.
Wasn't that one of the points of the show? Demonstrating that we people, places and events that don't line up with reality. Especially when time catches up with them. but that's unavoidable. No one writing for the show, from Roddenberry down to the guy contributing a one off plot set out to create an alternate history or future. That it is an alternate history/future is fannish rationalization that allows everything on screen to "fit". It's a bit like hording, they can't throw anything away.
