I sometimes look at small mass-produced plastic items and marvel at how hard it would be to make one from scratch. If you showed me, say, a fluted plastic bottle of wite-out with a screw-on cap, I would have to assume you had a very expensive operation up and running that was already churning these out.

In software we can put a few shapes on a screen in just the right context and people will believe there's an operation as sophisticated as the wite-out bottle factory behind it.
