But there isn't a more under appreciated technology in modern computing than digital displays. In fact, modern computing just isn't possible without them.

Any time you see a pixel light up, you are witnessing actual witchcraft before your eyes - light bending through electric crystals just so you can read a tweet in bed. ╌╌╌╌ Before we can understand where we are, it's helpful to understand where we started.
