In my view creativity, humanism, and ethics are very hard to teach, whereas worldliness and many other skills supposedly taught through the liberal arts are more easily self-taught in a continuously updating fashion if one has a good quantitative, logical and scientific process-oriented base education.
I agree with the first clause. Creativity, humanism, and ethics are incredibly hard to teach and harder to learn. But what is that supposed to tell us in the span of your broader argument? We ought to be focusing more on these things which are harder to teach, right?
