The same could be said for your brain.

LLMs are highly intelligent. Comparing them to spreadsheets is reductionist and highly misleading.

>LLMs are highly intelligen

I will tell you why it is not.

Intelligence is understanding low level stuff and using it to reason about and understand high level stuff.

When LLMs demonstrate "highly intelligent" behavior, like solving a complex math problem (high level stuff), but also simultaneously demonstrate that it does not know how to count (low level stuff that the high level stuff depends on), it proves that it is not actually "intelligent" and is not "reasoning".

You just invented you own definition of intelligence. I'm pretty sure that strategy could also support the opposite conclusion.

So your problem with the definition is that "I invented it"?

Do you have any rational objection to the definition? If you don't have, then I am afraid that you don't have a point.
