That said, still I'm open and curious... could you please be so kind as to elaborate how that education is very well-rounded? What would the studies yield more concretely?
I was able to complete degrees in COLA and a CONS simultaneously in four years with one of those four years being study abroad studying one subject to the exclusion of everything else because of it. When I graduated, I had studied two foreign languages and taken elective/upper div courses in poetry, immigration policy, ethics, mathematics, and computer science.
Unless things have drastically changed since I graduated, it still holds true for UT in particular, and is one reason I consider my education to have been so great.
I think the best outcome is to have such students crush their standardized tests by outperforming them due to having a higher baseline because of the interdisciplinary program's curriculum.
Even just putting together people from different background and trajectories can do miracles sometimes.
(Data science also sometimes gets the "CS lite" label, but Stanford's program looks like it might be somewhat technical and closer to scientific computation.)
