Very little that is made becomes "timeless". There is always something to succeed it. The pre-2009 Star Trek franchise has already become "dated", just as Star Wars has. There's no real disappointment involved with watching a supposed future time not leveraging tech as good as what we have today, because it's not real. It's a "possible" future, one of many.
Have you seen Fringe? There was an alternate universe depicted and you see airships (dirigibles, or "blimps") docking with the Empire State Building, as was originally intended. It could have happened here... but it didn't. The Star Trek we see is just one interpretation of a future. As long as the stories and acting is compelling, it's fun to watch regardless of how "true to life" the technology is.
