I wouldn't be surprised if we develop brain uploads sometime in the next 400 years, at which point the focus on trying to recreate earth-like environments anywhere will look silly.

Our current view of space colonization is probably going to have as much of a connection to the future as the Tower of Babel had to the Apollo program.
