"Torched"? Nah, not at all. But the donut tutorial is famous for a good reason. A donut is basically a torus, which is one of the basic shapes that Blender gives you, so you're starting from a shape that's nearly right — and then the tutorial teaches you how to deform it slightly so that it looks less perfect and therefore more "real". Which means that you're learning the process of modeling. That same tutorial then teaches you the process of texturing, of lighting... By going through the process of crafting an object you don't actually care about, you learn the steps involved in crafting the ones you do care about.
