I feel like the movie could have done a better job at conveying the state of the world. The focus of the earth stuff was so heavily restricted to scope of about 5 characters with only vague reference to what year it was, how many people were still alive, what governments were still around, and who was doing what and where to survive in this world.
Film was already long as fuck and while interesting to know, it's not vital information. Besides there were good little jokes such as the New York Yankees, that portrayed the state of the world. We also knew from the step-dad's speech that the number of humans is way down.
In fact Cooper states there are million of families depending on him so chances are good that the population total is near or under a billion.
Cooper station was named after Murphy Cooper. No one knew of the mission, cept Murphy. She was also the only one who learned of the who the ghost was.
Yes but Cooper himself was famous too. There was also a plaque to the Lazarus mission. Cooper's mission was known.
