An LLM by itself is not thinking, just remembering and autocompleting. But if you add a feedback loop where it can use tools, investigate external files or processes, and then autocomplete on the results, you get to see something that is (close to) thinking. I've seen claude code debug things by adding print statements in the source and reasoning on the output, and then determining next steps. This feedback loop is what sets AI tools apart, they can all use the same LLM, but the quality of the feedback loop makes the difference.

It's still just information retrieval. You're just dividing it into internal information (the compressed representation of the training data) and external information (web search, API calls to systems, etc). There is a lot of hidden knowledge embedded in language and LLMs do a good job of teasing it out that resembles reasoning/thinking but really isn't.
No, it's more than information retrieval. The LLM is deciding what information needs to be retrieved to make progress and how to retrieve this information. It is making a plan and executing on it. Plan, Do, Check, Act. No human in the loop if it has the required tools and permissions.

Given the fact that "thinking" still hasn't been defined rigourously, I don't understand how people are so confident in claiming they don't think.
reasoning might be a better term to discuss as it is more specific?

Isn't that still "not thinking"?
Depends who you ask, what their definition of thinking is.
Just ask it how many r's are in strawberry and you will realize there isn't a lot of reasoning going on here, it's just trickery on top of token generators.
This is akin to "Show a human an optical illusion that exploits their physiology".
LLM's be like "The dumb humans can't even see the dots"[1]

haha that's a great analogy!
How about non-determinism (i.e. hallucinations)? Ask a human ANY question 3 times and they will give you the same answer, every time, unless you prod them or rephrase the question. Sure the answer might be wrong 3 times, but at least you have consistency. Then again, maybe that's a disadvantage for humans!
Ask an illiterate person the same thing and they will fail badly too. Is it impossible to have intelligence without literacy? (Bonus: if so, how was writing invented?)
Yes but an illiterate person can be taught to read. Also LLMs generally fail (non-deterministically) at math in general, but humans can also be taught math.
