Am a civil engineer working in tech now. I never felt like engineering was magical, we studied materials and stresses and tested stuff and built things.
While I know software engineers basically do the same things in a digital concept (hardware included) they are basically speaking arcane words that make the machine do things like conjure up images, transport information across the world at the speed of light.
Maybe fantasy writers should write more infrastructure into their stories for their wizards, like undersea cables or satellites built by the generations before
It’s all wizardry. A long time ago some dudes tricked a bunch of rocks into doing math. So long as you don’t let out the magic smoke, you can keep doing math.
The trick is getting the lightning into the rocks first…
Also don’t forget to add the strange etchings to the metal disk
