If I were designing a core curriculum off the top of my head, it might look something like this:

First year: Statistics, pure math if necessary, foundational biology, literature and history of a time and place far removed from your native culture. Classics is the traditional solution to the latter and I think it's still a pretty good one, but now that we can't assume knowledge of Greek or Latin, any other culture at a comparable remove would probably work as well. The point of this year is to lay foundations, to expose students to some things they probably haven't seen before, and to put some cognitive distance between the student and their K-12 education. Skill at reading and writing should be built through the history curriculum.

Second year: Data science, more math if necessary, evolutionary biology (perhaps with an emphasis on hominid evolution), basic philosophy (focusing on general theory rather than specific viewpoints), more literature and history. We're building on the subjects introduced in the first year, but still staying mostly theoretical.

Third year: Economics, cognitive science, philosophy (at this level, students start reading primary sources), more literature and history. At this point you'd start learning the literature and history of your native language. You're starting to specialize, and to lay the groundwork for engaging with contemporary culture on an educated level.

Fourth year: More economics, political science, recent history, cultural studies (e.g. film, contemporary literature, religion).
