The premise set out in your headline drew my attention and the article lived up to it fully. I was fortunate to benefit from the Renaissance education model havinf won a scholarship to one of England’s elite schools (where I proceeded to be a disruptive influence for the next five years, but it is surprising how much of what was being taught actually stuck and is still with me almost 50 years later.
And yes, studying classics, literature, rhetoric, art history, music and comparative religions as well as history, geography, English and French, Maths and the natural sciences did make me a better computer programmer, systems analyst and eventually management consultant.
It surprises many people that somebody as useless at mathematics as I am could succeed in such a field, but another benefit of the education I had was the introduction to Boolean logic. And with an understanding of that and good arithmetic skills anyone can do well in business computing. Pure mathematics is handled in software dealing with engineering design or scientific and technical programming or in the gaming industry.
Thus I think too much emphasis is placed on maths by the STEM curriculum, resulting in a rather narrow mindset.
