Abstractions are ultimately a tool for humans to manage complexity in a particular class of problem, and to reduce cognitive load. Good abstractions come from imaginative human brains with taste and lived experience. Abstractions are also mind constructs that often have analogies in the real world. Even at the level of the CPU circuitry, abstractions serve that role. An LLM can only spit out what was already invented by humans and stitch it together in a tasteless, erroneous manner.
