One of my favorite comparisons is computing to magic. They say that sufficiently advanced technology is indistinguishable from magic.

A lot of people have a hard time drawing that comparison, but if you tell them that there are very special, rare silica rocks that you can only find in specific places on earth, and that if you inscribe one of these rocks with billions of tiny transistors runes and then power infuse the rock with electricity lightning you can actually make trick the rock into a processor thinking, and that this now let’s you create software incantations which explain to the processor thinking rock how to execute a program do specific things for you, then they begin to see why.
