To someone who only knows how to dig with a spoon, the notion of digging something as large as a trench will terrify them. All they know are spoons, so as far as they're concerned, digging is simply difficult. The only way they can imagine it getting any easier is if they change – digging with a spoon until they get stronger, faster, and tougher. And the dangerous people, they'll actually try this.

Peeling apples using a blade that could destroy mountains. Keeping light in the furnace using fire that could burn away oceans.
