With limited free time, it's hard to know whether it's better to self study or do a degree (or even just follow along a curriculum online)
I go between trying to work through things systematically to get a good grounding where I have knowledge gaps, and jumping to what I think will help me best on my job at this point in time.
It would probably be better to stick to one approach or the other to make more focused use of time, but I'm not sure which way is best! :)
I learned a lot of useful things, like how to write a compiler. But I would say that in the sense of what I really do day-to-day to "program", I'm effectively self-taught too.
(I walk the walk, too; I can and have hired people without degrees, and it's been fine.)
The only thing I've never had any use for is differential equations. I have for instance never worked with signal processing.
Still learned most of how to be a developer on my own, but I find immense value in the education. I learned to see how nothing in computing is magic, just hard work. In 2014 they changed the algorithm introduction course from C++/java to python, which I reckon is a good thing.
