There's a certain kind of techbro who thinks it's a knock-down argument to say "Well, you haven't built anything". As if the only people whose expertise counts are those close to the machine. I'm reminded (again) of
@timnitGebru 's wise comments on "the hierarchy of knowledge". >>
I've been pondering some recently about where that hierarchy comes from. It's surely reinforced by the way that $$ (both commercial and, sadly, federal research funds) tends to flow --- and people mistaking VCs, for example, as wise decision makers.
But I also think that some of it has roots in the way different subjects are taught. Math & CS are both (frequently) taught in very gate-keepy ways (think weeder classes) and also students are evaluated with very cut & dried exams.

How does one know whether the humanities are less gate-keepy? In some sense they have to be comparable, because the ratio of students to faculty is similar.
Wouldn't this mean that the gate-keeping is social rather than more obviously skill-based, and hidden, rather than open?
