Getting to Mars is a goal with many difficult problems along the way. But its kind of like building a nuclear bomb. The expertise and technologies developed could be immensely valuable to other industries. For example, it is said that SpaceX developed their own unique friction welding techniques for welding together two pieces of alloy. They share those techniques with Tesla. Who knows what kind of interesting innovations in rocketry, material sciences, biology, etc. will come up in trying to accomplish the Mars mission.
