I think the fundamental is the description of software as an idea. It is very important to understand, because it helps explains that the essence/idea part of software writing will never be automated and that any repetitive part in software must be automated to make progress. This is why the concept of software sweat shops/and some bad flavors of pair coding/agile development are stupid, it's all built around systematizing what should have been expressed in higher-order software anyways. They're only effective at still making money for the shop while the market hasn't caught up.
