After reading Midou's essay, the reason why Alaidi was satisfied and even moved was because the earth was very similar to their planet, especially Midou's sentence:

[We cannot survive if we leave the earth, but the earth is still the earth if we leave us.]

For the 2070 world, this sentence also applies.

Even if technology has reached the 2070 world, they still cannot leave the planet they live in.

Once, they thought that as long as the technology is powerful enough, they would definitely be able to achieve interstellar immigration, but the current conclusion made them a little discouraged because they already understood the mystery of the universe.

And what is the mystery of this universe is exactly what Midou will understand next.

"Let me guess, this is how your day on Earth..." Alaidi told Midou about his imagination of life on Earth.

In his words, adults on earth have to work and children have to go to school. The purpose of adults is to make money, and the purpose of children to go to school is to make more money when they grow up.

After hearing Alaidi's words, Midou was not very satisfied. He interrupted Alaidi and said, "No, we still have music. My father is a music conductor. He works for music, not for money. Also, my mother loves baking and flower arrangements. She always keeps the house in order. It has nothing to do with money! And, and, there is! I love painting, I can draw beautiful paintings, but I never thought of using it to sell money, so what you said is wrong."

"No, no, no, I have guessed your life, but you haven't understood our life yet. You have to know that when I was young, probably when I was as old as you, I also experienced the same life as you, but you don't understand why the things you see now become like this?" Alaidi finished speaking, deliberately paused and saw what Midou reacted.

He wanted to guess from Midou's eyes that this child understood what he meant.

Obviously, Midou understood, and he said, "What do you mean is that you are not satisfied with your current life?"

"Uh...I don't think you understand it accurately enough," said Aladi. "So, your life on earth is similar to that of us thirty years ago."

Speaking of this, Alaidi himself denied himself, and he added: "It's not right, to be more precise, what you mentioned about the experience on Earth may be a little behind us thirty years ago."

Aladi said while thinking, thinking about how to express his point to the child in front of him.

"You are still in the stage of pursuing wealth, but you know, we are a little more advanced. We have already reached the stage of pursuing efficiency thirty years ago," said Aladi.

"Pursuing efficiency?" Midou seemed to feel something faintly, and a picture appeared in his mind:

During a family fun sports meeting, the truth he understood was that if you want to run fast, you must remove things that have nothing to do with running.

On that day, the adults had one leg tied together, and it was necessary to see who ran to the finish line first, and to ensure that the children could not touch the ground. As the competition proceeded, only after running for 100 meters could the rope that bound the adult's legs could be untied, and the family of three could run freely, but the children could not touch the ground. Therefore, at this stage, parents still had to cooperate and take turns to carry the baby. After running for another 100 meters, the last 100 meters was to put down the child and let the child run by himself to see who arrived at the finish line first.
