I confess I haven't read this whole long article, but I find the ending very helpful. My emphasis added in quote below.

The Diff: Thinking-Things-Through Privilege, 2025-April-21 by Byrne Hobart

You can and should use LLMs as a way to refine arguments, identify examples, etc. But getting in the habit of doing that increases the utility of having good judgment about which beliefs and outputs to question. An LLM makes you smarter when you run your own writing through it and ask for weaknesses, but it makes you dumber if you just run every argument you disagree with through the same process instead. Models have reached a level of sophistication, and their moderation has been hobbled enough that they can come up with a cogent case for or against any proposition you can think of, if that's what you ask them to do. And that means that having the habit of asking the right questions, even when it's uncomfortable, is the only hope for being right.
