I am inclined to agree.

However, I'm not completely sure. Eg object oriented programming was basically a useless fad full of empty, never-delivered-on promises, but software companies still lapped it up. (If you happen to like OOP, you can probably substitute your own favourite software or wider management fad.)

Another objection: even an LLM with limited capabilities and glaring flaws can still be useful for some commercial use-cases. Eg the job of first line call centre agents that aren't allowed to deviate from a fixed script can be reasonable automated with even a fairly bad LLM.

Will it suck occasionally? Of course! But so does interacting with the humans placed into these positions without authority to get anything done for you. So if the bad LLM is cheaper, it might be worthwhile.
