Electronics using modern fabrication processes. If you think about how much science, knowledge, and R&D it took to even get to the point where these things are even possible to produce it is pretty amazing. We have developed processes that can reliably make electronics that are on the size 14 nano meters and falling. It costs billions of dollars to get a fabrication plant setup. Today you can buy a full, albeit stripped down computer, the raspberry pi zero for $5.
