The setting in the film is the future, but before the plot reaches NASA, you will feel that this is not like the future world at all. There is no advanced technology, but it is just like it was decades ago. Murphy said at the beginning that my father is a farmer, but who is not? Engineers, doctors, scientists, these are the roles that should have shouldered heavy responsibilities when disaster struck, but because of short-sighted decision-making (or brain-tickling decision-making, or plot necessity)... After the food crisis, everyone went to farm! ! The MRI technology that existed decades ago has been abandoned long ago, which led to the male protagonist's wife not discovering the tumor in time and letting go... Biotechnology is probably the same. It's not that it's underdeveloped but that humans have given up on it! As for space technology and NASA, I think they are the protagonists. It is also mentioned in the film that NASA is kept secret, otherwise it would have had the same fate as the MRI. In the end, it was the only remaining technology that saved mankind... If the only remaining technology was biotechnology, maybe the food crisis would be solved more cost-effectively, but that's another movie. So why do we still launch spaceships for fun when so many children in mountainous areas don’t have enough to eat and can’t afford to go to school? Do you understand? Wisdom is mankind's only competitive advantage.
