I think it's mainly a mindset issue, it certainly was for me for the first year or so.
That's when i completely stopped projecting my own hopes and expectations into the future development of ED.
Some (many ?) of us had this lingering feeling that "this time" or perhaps "next time" the game will surely catch fire and take off.
The big bang, the huge step forward, the shot in the arm, call it whatever you want.
It never materialized and it never will, the game is what it is. To expect it will ever turn into something radically different (or radically more exciting) with a single update/patch/season is a waste of time for those who actually still are caught up in that mindset.
After almost 5 years there shouldn't really be anyone around anymore clinging to that, if they have even the faintest sense of what has gone before.
This is not a criticism of the game. For all i can tell it has a solid player base, continues to receive updates and features, and is economically viable.
It also appears to me, that a majority of that player base isn't generally unhappy with how things are going.
The 2020 update will be welcomed by many, if not most, of them, and they will continue to play and enjoy ED.
But no, it will not be a milestone, "turnaround", or revolution of any sort, neither will carriers, space legs or atmo planets.
ED will still "just" be ED with all it's warts and wrinkles.
And if anyone after 5 years still believes it will ever be anything else, then sorry, i have to question your judgement.
