It takes a long time to accumulate enough knowledge to get the pattern recognition and competent creativity to be an expert in any field. Brains have speed limits. It'd be nice if the valuation of the field lasted long enough to make it worth acquiring and increasing that knowledge. Fun thought; what's it like to compete directly against 7 billion people? Do all specialized skills become close to worthless if you're not part of a restrictive "guild" (bar exams, medical board exams, etc) or part of a corporation?
