By the time we achieve technology where it is feasible for our species to utilize these exoplanets we will have sufficient technology for humanity to live normal lives without planets altogether. The future of our species is huddling around the warmth of the campfire (sun) and using raw materials from the asteroid belt to create structures orbiting the sun, until we create a sphere around the sun and all space is exhausted... then.. maybe after another few hundreds after that point, will these planets become useful. But not for reasons we would think. Perhaps for research purposes to see if humans then have the capability to tune back in to evolution after a thousand years of being pampered and letting the DNA deteriorate by eliminating survival of the fittest.
