Computer Science and Business. I say that with 15 years of experience in both those industries.
Business school is for people who couldn’t hack it in any other degree program.
CompSci is a legit subject, mostly as an area of mathematics, but doesn’t have a whole lot to do with building software systems.
The difference between computer science, computer engineering and software engineering is pretty nuanced in a lot of ways. Same core knowledge base. Sprinkle a little extra math and logic abstraction and you get a CS degree. More principles of development and team based work, and get a SE degree. More hardware and systems, and get a CE degree. And all three of them touch a bit on the other two.
More than a few of my team of software engineers and data engineers have degrees in things like chemistry or business. They just took a boot camp to learn to develop.
That may be more true today with more math heavy focuses like computer vision or neural networks. But most everything else is better learned on the job or via YouTube. Unless you plan to specialize like that, it’s almost certainly better to just teach yourself.
I’ve hired dozens of engineers from both university and self-taught backgrounds, and the self-taught ones are by far superior. In fact, it’s not uncommon that I have to break the bad habits taught in university - those courses are painfully outdated and the professors often have self-serving motives that hurt their students.
