Could most people stand to learn a little more about etymology, and read over their written documents more carefully before calling them done and sending them? Sure, absolutely. Again, however, this has always been the case. It’s just that in the past, lots more people couldn’t read or write AT ALL, so we have fewer records of the people who would’ve had “worse” language usage. And with the internet, we now have far, far more examples of language usage every day–every second–than we ever did before. The amateur writer, the professional, and the in between. This is, for linguistics, a WONDERFUL thing, because it’s far easier to track usage than ever before.
And though the grammar Nazis hate hearing it, common usage is what decides a word’s meaning. Not some sacred language council at a university, not the lexicographers who compose the dictionary’s editions, not The Complete Works of Shakespeare. Lexicographers track usage, and tally it up, and faithfully record it, AS IT’S USED, not as it “should” be used, and that is that.
Language is strong. Language changes. It always has. It’s fine. Don’t panic.
