Traveller can never actually be fixed is part of the problem. New versions and supplements get released or adapted into Traveller but there's always the flawed CT to fall back on that has the same problems that will cause the same discussions.
When you are very young, Traveller and Star Trek and Star Wars perhaps had a little bit of the "the future could possibly look like this" and as you get older it seems much less likely to the point of all three of those seeming absurd. Flaws in the assumptions of the settings stand out much more. The future is not going to be a massive recreation of the Age of Sail, there's no interstellar empire out there, the universe does not owe us a faster than light drive or the physics to allow it, and humans do not exist anywhere other than Earth and that may very well be the case for all time.
I'm not quite sure what Star Wars has that Traveller doesn't and it seems to suffer all of the same problems, but if you are trying to avoid living in the past and want to replace it with a hobby or interest that is more forward looking, what are you considering doing instead?
