This is what happens when everyone has essentially the same tools. Ever taken an intro figure-drawing class? You pretty much get 20 of the same drawing, except from different angles. Give 100 people flour, yeast and water, most of them will end up with some variation of bread--some better than others, but still basically bread. That's one issue--limited toolbox. The other is limited imagination: what do you do with the tools you have? What do you do when you know how to make a pretty good loaf of bread? Keep making the same bread over and over? Out of that 100 people, you're only gonna get maybe one pretzel.
