Anyway, here's a Minecraft player who—without the use of command blocks—has created a working word processor. That, it turns out, is also a thing you can do in Minecraft.

Minecraft processors use the physics engine of the game to recreate the structure of real processors on a macro scale, with materials including redstone dust, torches, repeaters, pistons, levers ...

This virtual word processor depends on a common element in Minecraft called Redstone, which generates and conducts electrical power.
