LLMs don't have reasoning nor internal logic. If you take a look at the "thinking" feature AIs like Gemini introduced, this becomes even more obvious. In order to have the most basic type of analysis possible, it must hallucinate an entire context window to force the language model to reach a specific conclusion.
There's zero world in which LLMs replace humans. They might, temporarily, be convincing enough to trick a few CEOs... But that period of time won't last long.
Now, a human being assisted by AI on Microsoft Word or their Python IDE, sure.
