I've found incredible value from studying the humanities, especially literature. Some of the courses I took in college completely changed the way I view and understand the world. Literature has been a constant source of inspiration for me, and without doubt has made me a more whole, critical, and creative person--something that has had a marked effect on my career in startups (Caveat: It helps having grown up coding alongside this, I suppose).
With that said, I found the author's examples to be terribly reductive. Studying liberal arts is not going to make you better at finding memory leaks or optimizing algorithms. Exposure to the humanities will, however, make you a more well-rounded human being and help you to contextualize and understand big-picture problems (vision, positioning, identity...the WHY behind the product) from a different (and, of course, not always better!) perspective than might typically be found at a company filled exclusively with STEM graduates. I agree with the headline and the spirit of the article, but it's too bad the author's defense of it doesn't stack up.
