We can only dream of such a world where those projects hadn't been funded. Along with the immeasurable wastage of resources, diversion of human talent, and theft of tax revenue.
I'm not a big Musk fanboy (anymore), but the work SpaceX has done is clearly ground breaking. I also wonder where electric cars would be without Tesla. They were all but dead after GM killed theirs.
Yes, but there's no doubt any and all of that could have been done in a way that's less harmful to society at large. Which isn't a specific criticism of Musk, rather of our corporate culture in general.
