Many people would argue that linguistics is one of those useless studies compared to comp sci, but it shares deep connections to research in logic and by extension type theory (see handbook for logic and languages)
Would it perhaps be prudent to cap the number of participants in those departments to match the number of real-world vacancies available?
A great video about open-endedness (warning - very long) with Kenneth Stanley, author of the book "Why Greatness Cannot be Planned"
unless youn disagree with the laws of supply and demand, it seems the market consensus at this moment is that compsci majors are far more useful than any fundamental research (which still remains undefined).
Even if the market was wrong and fundamental research could somehow be valuable, why would you not trust the primary beneficiaries oj making that decision, vs some bureaucrat that has no stake in the outcome?
