LLM literally is neither 5 year old kid, nor a machine. It's just a large math equation that was tuned to produce outputs similar to what humans produce.

If you choose to think about LLM as a machine you are biased. You expect from it things you'd expect from a machine. Reliability, repeatability, utility, indifference, etc. You pass your past frustrations with other machines onto LLMs.

If you choose to think about LLM as well read 5 year old you are also biased to expect from it different things. You don't have the same frustrations. You have different behaviors towards it. Behaviors that accidentally are more conducive to drawing value from the tool that is LLM.

We perceive the world through metaphors. If you pick wrong (counterproductive) metaphors you end up being constantly upset by something that's just a math result. By no ones fault but your own.
