Silicon is basically refined sand. Sand whose value is effectively 0. Refine it into a silicon wafer, etch it into semiconductor chips with a few billion transistors each, and that wafer of a few dozen chips is worth tens of thousands of dollars. If your imagination limits "resources" to bare materials, yes, of course they're limited—though there's an awful lot of sand in the Earth's crust. But it's a stunted view of economics, so stunted as to be worthless as a model.
