I believe that the excessive use of LLM's doesn't just lead to a lower IQ, it is extensively used by low IQ people in the first place. One guy I know, who is heavily reliant on these LLM's, explained how a large thesis should be broken down into smaller chunks with the opening statements and conclusion be fed to the LLM first, with other parts of the thesis entred into the software later and separately. Thus, the user needs to read the thesis first prior to being able to use the LLM, defeating the entire purpose of using it as an analytical tool, as the reader will have come to a conclusion already. And his post was written by Ollama, which was quite clear due to wording and structure.
An electrical engineer complained endlessly yesterday in a technology group I'm in about how these tools are unreliable and constantly give erroneous data and analyses. He said that they have stopped using LLM's as even purpose built LLM's by Siemens and Bosch can't recognise their own products and create proper graphs.
I can't find a single use for these LLM's that can't be done better and more efficiently without these tools. It might be possible to write code but considering it's been reported that it takes more time to correct errors than it would had the code been written by hand, I believe that the only people who are 'more productive' through the use of these tools are not qualified to perform their tasks in the first place.
