2050 is not meaningless. Its close enough to feel like its achievable but far enough away that you can put off immediate action and still feel there is time to get it done. Reminds of the lyrics of the spirit of the west song:

It's a ways outside of town

But the distance has its uses

Close enough to make the effort

Far enough to make excuses.
