As someone who took calculus, linear algebra and a couple CS related courses on my economics program in university 6 years ago, I wish I had someone around who could explain me (better) why and how all those courses can be helpful to me. ML and AI were not big those days (at least I didn't hear much about them as I do know). Now, looking for my first python web developer job and dreaming about switching to something more ML related eventually, I am thankful I hadn't completely fail those courses, but feel extremely sorry I didn't study them properly.
