Funny, I said something similar at that parenthetical remark. I thought to myself - oh, it was only a little remark, no-one will catch it! So I'm a bit thrilled, the careful readers are still out there.

Absolutely, to what you're saying, and I think it's another of those cases where often people know the "meme" (about the medium being the message), but then haven't the first idea what it means - unfortunately. For example, with smartphones, the message is humans as silent consuming spectators and fans - sitting silently, staring, swiping, scrolling, mildly stressed and agitated and worked up sometimes even but not wholly aware of it, maybe mumbling something to whoever is around every now and again.
