Star Wars gets away with it because its a fantasy realm, its not in any way shape or form connected to our Earth or galaxy. Its medieval knights in space or something..
Uhura got it right in Star Trek III
,"This isn't reality, this is fantasy!" Star Trek has always been more fiction than science.
Yep. I don't see this as an issue at all. Star Trek is as much "space fantasy" rather than sci-fi as SW is. I don't see it becoming out of date, and they can always make it so the Trek universe is in a slightly different reality than our own to explain discrepancies when things like "first contact with the Vulcans" doesn't happen in 2063.
Folks still like the "Terminator" and "2001" series, and those are very inaccurate now.
