What's your understanding of the ending of Passengers?

Is to be together until we are old. There are several reasons: finally, the lens hall is blocked by trees, which shows that the hero has planted many trees alive; The hall echoed with the heroine's monologue, indicating that this woman is awake and has been with him a lot; The robot transports the selected things in the corridor, which shows that they intend to live together before making this thing. So to sum up, they have been together until they are old, and they should not die in the end, but they are very old. Because the robot has been transporting vegetables and fruits, otherwise the robot made by the hero can't be moving all the time, right?
