On the need for colonization

There’s a post I’ve been meaning to write for a couple of years, about how the usefulness of the universe to our kind of life peaked before we were even on the scene and is now in rapid decline. ¬†About how Earth probably only has about a billion years of useful life left in it, and how stars don’t last forever either, nor will they continue to be born forever, and how the galaxies are gradually escaping our reach. And about how even matter itself will eventually disappear, and we had better saturate the universe with smart people long before that, both to solve that problem and to maximize enjoyment of life and appreciation of the universe.

But fortunately someone else saved me the trouble.
