Sounds to me like you're not describing its limited usefulness in general, you're describing its limited usefulness when as considered a tool.

That might seem like a distinction without a point but people are not tools and people are useful. If someone argues people are tools then they don't fit your definition any more than an LLM does.

LLMs are as useful as people I would say, and as unpredictable. I run a small consulting company and we develop custom software for businesses, government, whomever. I often have to interface with other teams and other people. To get the most out of working with people you have to know how to talk with them.

Also, I noticed you didn't say anything negative about LLMs :) You just compared it w/ tooling. So I'm curious, do you think outside of the unsuitability of consideration as a tool, do you find LLMs useful?
