What a short-sighted attitude. Colonizing Mars opens the door to a lot of advances in many, many fields. At first it will be difficult and expensive as it has happened with every new advance in the past. Precisely because of it, people will think of ideas to improve all the process and related problems. And presenting those new problems that we aren't facing now can lead to solutions that could be used in other common areas that we are used to and are kind of stuck.
