Turns out education done right is vaguely a speed-run of how the knowledge was developed. Adding calculating tools makes sense as you advance the the corresponding point in the process. Honestly, I think there should be a chunk of precal and calc where they use slide rules only, then calculators of increasing complexity (or just increasingly complex features of one calculator). "When will I use this in real life" is a declaration that you have no expectations of learning the next lesson that builds upon this one.
