You need to be more specific: are you talking about undergrad classes in person, online, or something like grad school? Why do you think that knowing graph algorithms is going to help you load voxel medical models (not graph structures, unless you're talking about image pyramids). GIS data viewers need a lot more klnowledge than just graph algorithms as well.
I think the most valuable thing you get from studying “computer science” either formally or informally is the shape of the literature and how you use it. There’s a rare interview question that can’t be answered with “look it up in the hashtable” or “look it up in the literature.”
One of my regrets is life is I never took a compiler class, I work at a university and can take a free class once a semester so I may rectify it this fall.
Still I taught myself a lot of that in the school of hard knocks.
I learned to read at three and got crazy well read checking out ten books a week from the public library as a kid. (Started my heavy backpack training!)
A lot of people fall for charlatans like L. Ron Hubbard and Eliezer Yudkowsky because they aren’t well read and don’t have anything to compare Dianetics and Sequences to.
