Humans also use scaffolding to make better decisions. Imagine trying to run a profitable business over a longer period solely relying on memorised values.
We dont need a more intelligent entity to give us those rules, like humans would give to the LLM. We learn and formalize those rules ourselves and communicate within each other. This makes it not scaffolding, since scaffolding is explicit instructions/restraints from outside the model. The "scaffolding" your saying humans are using is implicitly learnt by humans and then formalized and applied at instructions and restraints, and even then, human thay dont internalize/understand them dont do well in those tasks. So scaffolding really is running into the bitter lesson
