It is not as this new tech will enable us to see or take pictures of these exoplanets. In fact we will never be able to make technology that is able to do that from this system. There simply isn't enough data in the photons that reach us to do that. What we are doing is that we are creating instruments that is able to pry a little more data out of the few photons that do make it here.
We are not even able to take pictures of any decent quality of most of the planets, dwarf planets and moons in our own system. We have to send out probes to do it. Take Pluto for instance that we have not yet visited. Here is the best picture we have so far:
We can do of course is send probes, but I am sad to say that we will not be able to do that to other systems while I am alive. But we will get better pictures of Pluto next year. May 5, so clear your calender :)
So...we will be the blindfolded kid in the candy store. Dunno if that is worse or not.
