So, what exactly is the point of the LLM if it can't exceed an average person and produces results which are not trustworthy?

"The average person" has a job. Those jobs can now be performed by machine. The societal implications are profound.

If those jobs consisted of solving small isolated puzzles and math questions you'd maybe have a point.

The societal impact so far has been mostly increasing noise (generating irrelevant content you have to filter out) and burning resources.

Fundamentally AI models need a better way to learn and use memory if they want to replace entry level human jobs - RAG and fine tuning ain't it.

The "average Person" which struggles with the given questions probably has a physical work job though.

I think it's necessary to remember that they're not a general artificial intelligence, but language models. For example, they're pretty good (not perfect) at translating things, including translating arbitrary instructions into code or machine-readable forms.

Seriously? those are pretty simple HS math questions, I find it a bit hard to believe most average people cant solve them. Don't most people graduate HS?
