I was watching a show with Steven Hawking where he raised the best point about why we'll never really leave our galaxy.

He said that since it would take so long it would have no actual payoff for the generation who begins it.

That is a hard thing to commit to for a government. How can you tell your people "We're going to spend billions of dollars, and send hundreds of people deep into space where we will never ever ever know what happens to them - because we will all be long dead before they get to where they're going."





Edit: I also don't believe we're going to destroy ourselves. Humans have a great desire to live. nearly each and every one of us wants to live. I don't think the world will ever be destroyed by humans. I just think humans like to try and control other humans by threatening total destruction and the like.
