Yeah... They used side rules and vast lookup tables of function values printed on dead trees. For the highest value work, they painstakingly built analog calculators. They very carefully checked their work, because it was easy to make a mistake when composing operations. Humans did those things by designing failsafe processes, and practicing the hell out of them. What we would likely consider over fitting in the llm training context.
