Feeling defensive, eh? Thanks for informing everyone you're "literate" and therefore better than those filthy ordinary people. Pick up a newspaper, and tell me how much writing would actually be *improved* with a machine writer, eh? Writing isn't sacred, it's just another occupation like woodchopping or running the cash register at the 7-11.
What you describe is "everyday" writing. This is like the vending machine that reads "insert dollar bills face up" or "team A scored 10 points while the opposing Team B scored 15." It's purely practical, get-the-job-done sort of writing where only the technical correctness is important.
Writing can also be beautiful, powerful, and artistic. A well-written editorial, penned by someone who has a deep understanding of the issues, can and has moved entire communities to change their minds on important issues. A beautifully written book tells the perceptive reader as much about the mind and spirit of the author as it does about the story that is being told. A horror story requires some sense of what is horrible.
The ability to both produce and appreciate good writing is on the decline. Measured scholastically, the grade-level at which the average American reads and writes is significantly lower now than it was say, 50 years ago. A good look at many online forums will also tell you that this skill is not highly valued. You can say that's because only some cultural elite are capable of enjoying it, though the GP made no such claim. You can also say that there is simply less interest in such things.
You can invent and try to substantiate any number of unique explanations for it. The truth of the matter is that in most situations, challenging your readers is now considered highly undesirable. They'll read a competitor's paper written in simpler langauge before they'll grab a dictionary. There was a time when this would have been viewed as laziness and an unwillingness to meet a worthy challenge. It would have been viewed like a wasted opportunity to better yourself that should not have been passed up, just like most people today would not like to pass up a higher-paying job. I'm not saying that previous generations were one homogeneous block who all felt this way, but many more people once did.
Over the last few generations, some kind of cultural shift occurred. People now care much more about avoiding the small-but-significant effort of learning something new than they care about improving important skills. They generally won't do it at all unless it's required by an authority like a boss or a professor. Even then it's in a rote, mechanical sort of way that deprives them of true appreciation. Even then it's reluctant, with a "gun to their head" in the form of losing their jobs or failing school.
Can you comprehend how sad that is?
