I guess we're redefining "the scientific community", cutting out those who were wrong each time? Do you consider the French Space Agency (CNES), former NASA Administrator Charlie Bolden, the European Space Agency to be part of the scientific community? I still vividly remember one interview where Elon started to tear up because Neil Armstrong and Gene Cernan publicly denied the feasibility of SpaceX's mission.

"Scientists" being detractors and everyone going online to comment about how something is impossible while the people doing the thing just do it then all the detractors quietly shrug it off until the next time is so consistent it feels like Groundhog Day. I'd really like to learn about why so many people get off by saying something that other people are working on is impossible.
