If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
Alternately, learn to upload people. Which is still probably going to require nanotech. This way, you're not dependent on ecosystems because you don't need anything organic. You can also modify computers to be resistant to radiation more easily than you can people.
If we can't thrive on a wrecked Earth, the stars aren't for us.
