This is part of the problem being described. You are part of the problem.

"Some people are bad at X" is not comparable—is not even in the same category—as "LLMs are fundamentally incapable of X".

Every human (at least to a first approximation) is capable of understanding, of learning, of remembering things, of doing math, of counting the number of "r"s in "strawberry".

What you are observing is that some humans are careless, do not take the time and effort to understand, or have internalized the idea that they're "not smart enough" or "not the type of person" who understands things like <whatever>.

That has nothing remotely to do with the fact that LLMs have no consciousness, no self-awareness, no cognition, no understanding. At a fundamental level.
