I went to a private high school that prided itself in its English (writing) classes[1]. I didn't know it then, and I wish I had found out sooner, but I loved writing.
I started to realize this in college. I went into university as CS and picked up a Philosophy dual major after one semester so I could write more.
During my final year, in every single interview I had I made the argument that mere communication is massively underrated in engineering fields and that my Philosophy degree (or rather my writing skills) made me a better communicator than most other software engineers. I think I can safely attribute this to at least a few job offers, as the argument seemed to take a lot of interviewers by surprise.
After my college experience I certainly think the two majors (or any STEM major plus a writing-heavy major) compliment each other. CS and PHIL as a combination seems only natural from the get-go, especially with the intersection of Logic. But I especially think PHIL compliments CS because in my opinion the largest deficiency in every other CS and engineering grad I've met is that they have a hard time communicating their ideas and debating others effectively. Philosophy (all writing really) helps with that. A lot.
I think writing out anything, even just your own thoughts on a subject, makes you a vastly more empathetic person, something most engineers I've met seem to desperately need. It's mind-boggling the amount of extremely smart people I've come across that nonetheless seemed to simply lack the concept of not-them.

[1] The article says "The program would not be unfamiliar to nuns who taught in Catholic schools circa 1950." I had 12 years of Catholic school, though not in the 1950's, I graduated HS in 2006, so I imagine some of the curriculum theory stayed put.
[2] I've found myself considering the humanities majors I've met far, far more socially capable than the engineer majors, almost to an embarrassing degree. I've always been quite the introvert, supremely shy as a child, but was totally unprepared for just how shy I would find others. My college (RPI) was known for being an introverted place and I met so many great people who almost literally never left their rooms. Great minds and personalities who were self-sequestered from the world.
It felt tragic sometimes. I met and found a lot of people that wanted to meet others but had a great fear of simply being in public spaces more and exchanging pleasantries. Others still, and this was not an uncommon opinion, would disparage the idea of small talk as useless. It's funny but, of all places, once I came to college and met enough varied and amazing people I became vastly, vastly less shy. It just wasn't worth it to be shy when there were so many great people to meet and listen to.
