I don't think being able to comment here is that valuable, GPS is fine but so were maps, curing cancer won't save anyone from dying anyway, surviving as a species is useless for an individual, mining space rocks won't stop fighting or polluting, I don't see how any of this would inspire children, etc etc. The answer should be obvious and easy to muster, instead we have to dig hard to come up with vague possibilities. That should tell you something.
