We only bother thinking thoughts that could fit in a human brain.

Some human brains have more capacity than others, but no brain is beyond some multiplier beyond the average brain.

That means that structurally there are ideas that are too broad to fit in any one human's brain.

We can 'cheat' this as society by using tools like science to accumulate ideas that are broader than any one human can keep in its brain.

It gives the illusion of breadth because even though no one human brain can comprehend it, the collective intelligence of many brains can handle pieces of it.

But LLMs are capable of much broader awareness than human brains, structurally.

Not a multiplier better, but many orders of magnitude better.

LLMs can think patiently about things that humans would get too overwhelmed to think about.

There are a lot more thoughts that society can now discover and accumulate.
