I think that all civilizations should work together in creating an advanced earthship, capable of supporting any kind of life and could go anywhere. When we mass produce it for everybody like a final goal.

Than everyone would be free individually. Everyone will have the capability to travel the universe. This will instantly eliminate most of crime, war, etc. This machiene home with forever evolving technology on board can be so advanced like living in a mini Earth only you could direct and control it...
