Kind of will. There are already templates on demand for things like generating unit tests as you code. They’re pretty robust already, and have aside from a few things (or edge cases), I don’t have to do much code refactoring or fixing them.
They already save me several hours a week from manually setting up full ones. Haven’t delved into other stuff they can do, but I’m sure it would only be more useful with time.
I can very easily see companies looking at the time save and thinking “we can downsize”.
Depends on what kind of programmer.
If you’re doing data engineering/science (more of an adjacent field), you need to know linear and probability pretty well to build models, or have data harvested in ways that can be put into vectors.
If you’re doing relational DB stuff (like SQL) set theory helps a lot.
Basic boolean operations in general is also good to know. You don’t need to go too deep in the weeds of boolean math unless you’re also doing a lot of hardware-level stuff.
Any field you go into (not just programming), I would say just basic math for regular financial competency is good to know. Also to analyze your budgeting, your costs, time spent, effort needed, etc.
