I learned java 7 in college, got a job writing java 7 transitioning to java 8, then spent 8 years writing python 3, which when I actually got the job I thought I hated python (I think it has some dumb choices and culture around it), and through some slow but definitive moves in that same company I "learned" java 8 to start working on a different project.

I was expected to learn and become proficient in things like CSS and Javascript and HTML as well despite never taking a class on any of them.

My degree taught me how computing works, from the theory to the logic gates to the math needed to interact with basics in the field.

You know, companies used to spend money "training" their employees to do the things they needed to do. When computers first came around companies had to turn a mountain of secretaries into the very first programmers and computer administrators, and those mostly women bootstrapped the entire information economy. But that investment into human resources could better be spent on the CEOs private plane so they've spent the past 40 years bitching that "waaah waaah higher education doesn't make me cheap little worker bees waaah" as if you are entitled to free labor just because you "run" a business
