Space-faring for humans is apparently going to be necessarily cost effective. Since humans are unable to accomplish anything without a positive ROI we're going to need to make space mining lucrative. Once it gets to the point where mining asteroids is more cost effective then operating a terrestrial mine we will see vast explorations into the far reaches of the solar system.
no joke - if EVE is any example then asteroid mining is gonna be way important, if for no other reason than to give pirates something to lock.
If it happens once, it's a bug. If it happens twice, it's a feature. If it happens more than twice, it's a design philosophy.
