Thanks! I came to a similar conclusion while researching historic science undergrad syllabi, especially but not limited to Physics. Nothing much (apparently) has changed in Math or Foundations in these subjects.
I used to study CS papers/topics on my own, but then figured a major university to be better able to provide better constraints than I ever could.
I sometimes write about stuff I care (and feel that need to be published) on medium (like 2-4 times a year).
For most of the time I just write markdown files that I keep locally.
