Chrono Trigger is this many years old and it's still not normal to be able to walk away from text boxes.
Never take control away from the player unless you absolutely have to. (E.g. A game over. Also, archive the cutscenes, e.g. FF Tactics.) If your player isn't paying attention to your story, that's your fault, not the player's problem.
Is the above principle some 200 IQ galaxy brain transcendence that nobody can possibly understand? Is the purpose of NPCs, as far as game studios are concerned, to waste your time and/or browbeat a captive audience? Or is advancement really this hard?
