If it happens, people would cry with tears of joy, sure. Then whatever is theorized in extremes such as Star Trek, V, or anything in between that neat little range won't be as entertaining - much less useful as "how-to guides"...
The law of probability is still insurmountable, and there's a few fun theories as to why space travel to reach other civilizations so remote is that way. Not to mention temporal equivalence; not all civilizations develop at the same rates or at the same times. Many that might have will have gone long since past. Or have yet to get that far to make such lengthy distances traversal within tangible spans of time. Okay, multigenerational transport is also possible but also hosts its own set of issues.
