Interesting tidbit about the V2: as far as I know it's the only weapons system that killed more people during the manufacturing process than it did in actual use. Casualties caused by V2 strikes are estimated to be around 9 000, but around 12 000 slave laborers died making them (see eg the wiki).

In any case, comparing von Braun to Musk is uncharitable towards von Braun: he actually did design rockets and knew what he was doing, where Musk is just a bigoted windbag that emits money. But I do tend to agree with your sentiment though: SpaceX has good designs, but that's completely separate from Musk being a human turd (and his only part in it is the part where he emits money.)
