Futurology

"Ever" is a long time. Human progress seems to come and go based on need and economics. At the moment we seem pretty distracted by local problems and I don't think any of us will still be around by the time humans kill the Earth, so it doesn't seem all that pressing.

But someday the technical issues will be solved and a sustainable habitat will be able to coast through space for however long it takes to travel beyond Mars to somewhere else interesting. When it's possible, I think some people will do it, perhaps a lot of people.

It's a worthy goal. As a human I feel some motivation to ensure the continuation of our species so I would lean towards any efforts that involve sending some backup copies of our DNA to some off-site storage.
