Pretty long stretch between "useless" and "completely satisfied". I don't think I'm completely satisfied with anything in my life including AI, but that doesn't mean I'm not having a lot of success with it.
The things stated in the article are true and even pretty tame. Agent mode in Cursor has been standard for months and I'm surprised that anyone would say that LLMs are not good at scanning documents. The normal AI skeptic's position would be "yes, but that's all they're good at".
My personal experience with any approach I tried ended up in a semi-failure state. I can't trust LLM and have to check everything myself to either actually solve a problem or be sure that the LLM did not invent things. This fact simply kills the usefulness of LLMs. They are not reliable and I waste more time trying to accomplish something just using the AI. If people around me were praising AI and I was the only one unable to find an approach, I would agree with your points. But it's not the case. The general perception of the AI tools is quite pessimistic.
