I'll help you out: all CS students are required to take an entry-level OS course. Again, you are making incredibly weak arguments given that most students are required to take an English writing course but then can't remember most of it.

It isn't that they didn't learn it: the issue is that most CS students graduate and work in areas that require zero OS knowledge. For example, when would I spin up a thread versus a fiber? Even ring-3 devs need to have some level of understanding if they want to create performant software.

First, I didn't work with the right universities. Now the students I work with "didn't pay attention".
