Yeah, I was mainly just being facetious about how what you described has "been a thing" for decades, and there's a whole industry around it (in which I've earned my living this century). So if you thought your insight was new, you'd be disappointed... :-)
But, come to look at it in hindsight, my comment may have been misplaced -- maybe it should have gone as a reply to the same comment you replied to, with its "It really is amazing how far you can get..." At least if they meant "amazing" in the sense of "surprising". To me, what's amazing and surprising is only how many people don't already know this.
