Stewart's attitude is unfortunate. It seems to me he's got it quite backwards...ignoring humanity's future in the cosmos is not only the heighth of arrogance, but is irresponsibly short-sighted.
I would like to see us get this place right first before we...put significantly flawed civilizations out onto other planets...
Geez Louise, Pat! Humans are flawed! Get used to it! If we put everything else on hold while we try to "get this place right first," we might as well glue our feet to the ground, 'cause we'll never go anywhere.
