Star Trek is honestly 'Space Fantasy'; there's so littl in it that is realistic to begin with, I don't believe it's a fair question.
We will not have interstellar space travel akin to the way ships sailed the oceans of earth in the past. It will nev er be easy, cheap or fast; and althiough we may one day find an actual Earth like planet we could travel to, it would require decades of testing to see if Humans who evolved on earth could survive there.
