I agree. I love Star Trek as much as anyone, but I think that, realistically, interstellar travel simply isn't possible, and that even if there is another sentient advanced species "out there" that never the twain shall meet. And even if interstellar travel is actually possible, you have to have the will to actually do it, which I doubt that we do. It's been over thirty years since any human has even ventured out of low earth orbit.

Interstellar travel is possible (there isn't any magic wall keeping us in the Solar System). The question is, is it practical?
