I completely agree. Bricks would be a better metaphor and still completely contrived. And turns out, you can't build skyscrapers without concrete and steel :) And just to be pedantic: When I bought my first SwissTools Insider[1], I realized that it's actually still possible to innovate in screwdriver design. That doesn't make them better for every task, but hey, that's the way it is.
