Should we A) colonise other planets or B) build habitats in the middle of space, like O'Neill Cylinders and stuff?

Until we are able to travel way faster than what we can do now, I think it’s more feasible to build in space. Lots of implications for long term effects on human bodies though. Most ideal is a wormhole to an identical planet to earth so humans won’t need to adapt.
The odds of an exactly identical planet existing naturally are very slim. The only way to get that is some kind of terraforming. Or we evolve to adapt to our new environments. Which could mean that humans could split out into multiple successor species.
