I'm not sure I agree with this article's idea of what "good thinking" is. To me, good thinking is being able to think logically through a problem, account for detail and nuance, be able to see all the possibilities clearly. Not simply put vague intuitions into words. I do think intuitions are important, but they tend to be only a starting point for an investigation, preferrably an empirical one. While intuitions can be useful, trusting them is the root of all sorts of false ideas about the world. LLMs don't really help you question your intuitions, they'll give you false sense of confidence in them. This would make your thinking worse in my opinion.
