I'd argue that most humans are terrible at thinking. It's actually one of our weakest and most fragile abilities. We're only rational because our intelligence is collective, not individual. Writing and publishing distribute and distill individual thinking so good and useful ideas tend to linger and the noise is ignored.

What's happening at the moment is an attack on that process, with a new anti-orthodoxy of "Get your ideas and beliefs from polluted, unreliable sources."

One of those is the current version of AI. It's good at the structure of language without having a reliable sense of the underlying content.

It's possible future versions of AI will overcome that. But at the moment it's like telling kids "Don't bother to learn arithmetic, you'll always have a calculator" when the calculator is actually a random number generator.
