I'm always puzzled by the hate for Elon Musk. Obviously, no one is perfect and can be criticized, but invariably the reasons given for Musk's perceived "lack of success" are quite irrational. As is often the case, it seems jealousy and envy are the main drivers of criticism.
Even only counting Musk's failures, he has achieved a lot more than most. Building a successful space company in a short time, plus with new technology advances and a reduced cost, is remarkable.
Although, I am interested to see if these "backyard rockets" become a viable space ship. Rapid prototypes can appear to be failures, but it's the fear of trying something new that enables Boeing charging $2B for a single rocket launch.
