It’s not about whether the abstraction is human or not, it’s the level of abstraction you can operate at. Using hand tools vs power tools as a bad analogy: you can use either and still become a good carpenter. If you have someone build your cabinets for you that’s a totally different level of abstraction and you don’t actually have any carpentry skills or knowledge.
I'm not making a mistake, you're confusing abstract "abstractions" with concrete humans. Some humans aren't much into abstractions but that doesn't make them less human. LLMs manipulate human-created abstractions, similar to other software, but that doesn't make them human at all.

You're confused about my analogy too, here's what I said: "a human digging trenches isn't a tool but a tractor-trencher is, even if autonomous". Robotic, autonomous tractor-trenchers do manipulate abstractions and dig trenches but that doesn't make them human.
