Strange New Worlds is unique amongst Star Trek shows, and shows in general, in that five of the nine main cast members have discernible fates. They *will* survive the series and go on to the TOS era relatively intact.
To a certain extent, all shows with heroes have this, but there is a level of uncertainty. What if Mary Wiseman leaves for a movie career? What if Jack Quaid has a salary dispute? What if Santiago Cabrera decides that Patrick Stewart is the worst, and they will never work with each other again?
With most shows, the sky's the limit on how to handle a character exit. With this show, and these five in particular, their hands are tied pretty tightly into reassignment. M'Benga, Chapel, and Uhura probably do work best if they're reassigned and come back at some unknown future period, but Spock (Peck) and Pike (Mount) are series enders, in a way that no character leaving in all of Trek could have been.
The amount of "safe" characters in SNW is an intriguing challenge for the writers and viewers alike. Of course, the show is also centered around a man who knows his own fate. Playing with fatalism and predetermination is baked into the premise in a way that I've never seen before.
