SpaceX has taken 21 years to get to this point. They have not failed fast. They have seen a long series of huge successes from doing some incredible engineering. Today's test is a small part of that journey.
SpaceX is a great demonstration of an "ideal mix" of new and old. It has a lot of "classic" "measure twice; cut once" planning, but also an absolutely essential "YOLO" mindset for live testing, which can cause big failures, but also give the most valuable data.
Their manned flights have been great (except for that toilet thing...).
