I definitely agree that mind wandering is where a lot of creativity happens and that it shouldn't be dismissed as just extraneous activity.
However, I think in this case, the author is talking more about this kind of mental baggage that people accumulate while scrolling through Facebook feeds and the like. We're essentially - whether we like it or not - memorizing crazy amounts of unnecessary information, and thus throttling creativity because we're still processing where Kathy went on vacation and what she ate there.
