Nah, even if space is totally boring, I'd go check it out. And I'm not afraid of dying. And I find dark voids comforting.
Plus, no matter how much cool stuff there is on earth, I'll need the means ($, transport, passports, bribes to corrupt border patrol agents, etc.) to go see it all. And that doesn't even factor in how much time it would take -- longer than my lifetime. Whereas, to go to space, I assume I get a fully-equipped speed-of-light ship for nothing (that is part of the deal, right? It better be). So I can leave right-the-hell now and go putter around the void for the rest of my life. And then, who knows... even if I find nothing, I'd no more be wasting time out there than I will back here.
