So? We are wasting our recourses on anything that is not related to propulsion. We know stuff is out there but we ain’t going anywhere with our current modes of going. Just sayin.
First we gotta find someplace worth going. I can all but guarantee you that the minute we find one of these exoplanets in the “Goldilocks Zone” has water and an oxygen atmosphere, the research effort will shift over to “how quickly can we get something there”.
Since there are people who are working on propulsion, that's just an absurdly stupid thing for you to say.
