Is there a meaningful market for them though? Do people actually appreciate them? Or is it just like LinkedIn slop (which I can only imagine has gotten immeasurably worse post-llm), which any half-thinking person disregards completely?

I suppose there's always been some market for LinkedIn lunatics, and likewise for any sort of "influencers", MLM, etc... And I've always written-off any of those people as well. Perhaps this is just a new flavour of the same thing...

Dumb people will continue to be grifted, and thoughtful people will continue to use these posts/materials as a good filter for who deserves their attention.

I don’t think we’re in a world of meaningful markets anymore. The idea is to get passed around on sites like these and on LinkedIn and what not until you reach somebody who’s gonna pay you money to be a contractor. And you know because they found you via your engineering blog posts that you’re not gonna have to do any real work, because the person was hooked on affect.

If a robot writes the blog post, then the economics become even easier because you could write a dozen of them.
