Excellent point.  Some years ago it happened with Math, when teachers handed students a calculator instead of teaching multiplication.  Soon the little darlings were pulling it out and punching buttons for 2 x 3.   It's a sad fact: too many people don't want to have to think, about grammar and punctuation or much of anything.  And the less thinking we do, the less we're able to do.  Maybe that's why our politics are so odd.
