I honestly would love to know how much money is 'wasted' by NASA because of these companies that seem to, over promise and then need a lot more money.
And I don't say wasted because I think that the money spent at NASA is not worthwhile. But how much else could be done if that money could be spent elsewhere or at the very least be properly estimated in the beginning so it could have been planned for. That money is (I assume) going to come at the cost of something else.
I really don't love the idea of SpaceX not having a serious competition. But... they kinda don't right now anyways it seems. I really hope we have another company step up to be anywhere near what they are doing.
