This. Marketing is a cancer on modern society, and it's metastasizing to new communication media increasingly quickly.

Marketing is literally customer/product (market) identification and all the activity required to produce and deliver the product to customers. Business. Did you mean advertising?

Are engineering, design, and logistics just sub fields of marketing? Is this really how people use the word marketing?

Motte and bailey. Marketing is what you say on paper, but nothing like it in practice.

(And people have been giving me identical response with "advertising" in place of "marketing" for years now, so I'll say yes to both; the terms are effectively interchangeable in both motte and bailey cases.)

Not if my company is paying for it. Which they will, because they have to. The price will be kept in check becauae it is a commodity. Anyone wanting enterprise business will have to include it (Microsoft 365).

Luckily, unlike search engines and similar, LLMs can be run completely locally. As long as there are corporate interests trying to squeeze new tech for every cent with no regard to anything else, there will be hobbyists making what's actually useful for them.
