That's how I read the article anyway. It is a bit hastily written, I think.
I think it's important to distinguish b/w ChatGPT and LLMs in general - I think he's using the former term to describe monolithic corporate systems, not all LLMs.
Not long, but yes. He starts out as if he has something to say, but doesn't, except to plug something at "I recommend ..." So it's clickbait.
His argument seems headed in the direction of declaring that advertising is bad, but he quits before he gets there. One can make a strong argument that advertising and finance, once rather small industries in terms of employment, have become much too large. They're supposed to be service functions for manufacturing and distribution. For many products, advertising is a significant portion of product cost. When promotional cost becomes a significant fraction of retail price, a company is in the self-promotion industry rather than offering a product. Perhaps tax policy should make this unprofitable. Arguably, it's a driver of unnecessary inflation.
"Advertising", viewed broadly, includes Google and Facebook. We should be thinking of the advertising industry rather than the "tech" industry.
Also I'd say the first part of the article is a general "the state of affairs sucks" kvetching that is repeated frequently these days in response to the AI surge, as evidenced by the two links. I find the use of the term "plug" in the context of linking those two resources a little needlessly pejorative lol - just illustrating his point quickly by citing existing literature.
