Astronauts need oxygen and they have the problems of human error. Yet if we use robots, well they do not complain, unless programmed too. Robots in fact could spend months to fix something, astronauts five day space walk missions are about all we can muster right now and if we cannot get it done in time, imagine the cost for another launch. What about fatigue factors, which take a toll on the organic components of the human body? Costs to send up a space crew to do repairs can be millions if not billions of dollars.

SpaceX says engine 1 had problems and was shut down. That the Falcon 9 survived the loss of an engine and still logged a nominal flight makes it the safest vehicle currently flying. Any other current launch vehicle in the world would have - given an engine failure - recorded a loss of mission. The flight survived what looks like a RUD of an engine.
