It's very obvious to me that today's problems are overwhelmingly technological, biological, mathematical, scientific, industrial etc. Even within these subjects, there's a mismatch between the concrete problems seen in industrial practice and the abstract and simplified ones seen in academia.
I hear the 'but any degree will give you a well rounded perspective' kind of hand wavy arguments, but these are presented without evidence, and are unfalsifiable 'runaway arguments' that have no finish line - at what point do you stop and say we're pouring resources into the wrong areas and neglecting others?
