Culd be my KJV upbringing talking, but personally I think there's an informative quality to calling it "vanity" over smoke.
And there's more reasons not to simply compare the modern challenges of image and media with the ancient grappling with impermanence. Tech may only truly change the human condition rarely, but it frequently magnifies some aspect of it, sometimes so much that the quantitative change becomes a qualitative one.
And in this case, what we're talking about isn't just impermanence and mortality and meaning as the preacher/quester is. We'd be lucky if it's business as usual for old planet earth, but we've managed to magnify our ability to impact our environment with tech to the point where winds, rivers, seas, and other things may well change drastically. And as for "smoke", it's one thing if we're dust in the wind, but when we're dust we can trust, that enables continuity and cooperation. There's always been reasons for distrust, but with media scale, the liabilities are magnified, and now we've automated some of them.
The realities of human nature that are the seeds of the human condition are old. But some of the technical and social machinery we have made to magnify things is new, and we can and will see new problems.
