What's the point?

Spelling class with Noah this morning.
Me: Spell "crocus".
Noah: C-r-o-a-c-u-s
M: Not quite.
N: Well, it doesn't really matter.
M: Why not?
N: Because it's not like I'm ever going to need to spell "crocus" in my life.
M: What if your wife wants crocuses at her wedding, and you have to write down the order for the florist?
N: By the time I get married, nobody will be writing anything on paper anymore.
He makes a good point.  It's unlikely that he'll be texting the florist anyway, but if he is, autocorrect will take care of it for him.  And even if he spelled it "croacus", the florist would know what he meant.  What's the point of teaching people to spell nowadays?
