Have you missed that they recently sent a rocket to moon?
Well, rails get made as well, I think the point was that a lot of things require reinventing knowledge that was previously known.
That happened in the reverse way. The government fired and underpaid a lot of people at Nasa ... and Musk hired incredibly experienced people, who became experienced on the taxpayers' dime, to build a rocket, for huge payrises.
The biggest but not only example: https://en.wikipedia.org/wiki/Tom_Mueller (yes, lots of subcontractors involved, however, Nasa paid, with a bonus percentage provided by the US military)
Note that Mueller gives the payment situation at TRW, and the fact that he "wasn't appreciated" as a direct reason to go to SpaceX.
What did you think happened? Does anyone actually believe Musk did the technical design for that engine, just because he claims so? Or I should say he constantly claims it, staying slightly away from direct claims to avoid getting caught in lies (well ... getting caught AGAIN).
This is the internet. You can’t expect HN or Reddit to be positive, especially around America. It was the same way before Trump was around.
These people and bots have no idea what they are talking about. They’re parrots.
They sent a module around the moon. They didn’t send a rocket to the moon. They still haven’t landed and their timeline keeps slipping.
