At the same time, if you can explain something by using analogies to real-world things, to systems most of us have an intuition for, then you can target many more people at the same time. It's true that this is harder, because you have to find patterns that are common between these systems and also make it clear where the analogy ends. But the benefit to finding these common patterns is that you also understand them deeper.
To give a relevant example, graph theory concepts can be found both in so many real-world systems but also in programming languages and computer systems.
