What's the purpose of summiting Everest if it's been done already? What's the purpose of summiting again if you personally have already done so before? We don't do these things only to be the first to do it, we do them because it's an incredible achievement, the first time, and the 100th time. Claiming that the new mission to the moon is a waste of time because "we already won the space race" is backward. Withholding an entire generation (multiple actually) from the awe and wonder that is associated with such an endeavour just because "it's been done before" is borderline criminal imo. And frankly, the fact that the US is struggling to get it's rocket in the air, let alone get a human on the moon, even after they did so already and literally wrote the tutorial on how to do it, is very embarrassing.
