Recalls a recent article (anyone have a link? been looking for it) wherein the future of human space travel is deemed nonexistent because lobbing humans to another place is so hard with so few places worth expending that effort for. Do we all want inter-planetary/stellar/galactic space travel? of course we say yes, but faced with expending a lifetime (or a thousand) to get there and burning all of Earth's resources to do it we'd say no. I'm fairly sure that was actually another blog post by Charles Stross, the author of this article. He also occasionally posts here as cstross, if you're looking for his comments on his work.
