A think a normal life the crew is something that they will most likely never experience. This is a, lack for better word; experience that even after they've completed what they've set out to do they won't be able to just walk away from it.
Like Chernaudi had said, they will probably be spending the majority of their time rebuilding/reshaping society and possibly wiping out Chronos loyalist. After that it will just be something as simple as ruling the world and maintenence.
