Neither does a Web app developer need to know how to use CNC or make a transistor. Your example is about different levels of abstraction than what I meant. I was replying to “even the known knowledge is extremely hard for talented university students to learn”. If complexity of the known knowledge one must learn to substantially contribute is the reason becoming an accomplished multidisciplinary is impossible nowadays, then it sounds like we could use some better models and levels of abstraction.
