One of the best pieces of advice I got in uni from a teacher on writing, which sounds pretty simple but can be tough to do, was: always write in your own voice. Writing is thinking, and when you're adopting phraseology, entire sentences and turns of phrases from others really you're not just sounding like someone else, you're not thinking on your own. You'll end up on autopilot, then metaphorically, now apparently literally. At an individual level people have always been doing it, now with automation it's not surprising that a study finds it happening collectively. That's why I don't see much good in these tools. They strip writing of personality, subjectivity, unique perspective, and they just seem to diminish the capacity of people to use their own minds.
