Whether that is due to technical advantages of type-theory over set theory, or a historical accident, reflecting the much larger amount of attention on type-theory as basis for interactive provers, is a subject of much controversy. Let me cite a leading light in the formalisation of mathematics [1]: &quot;I would guess that the amount of effort and funding going into type theory exceeds the amount that went into…</p><p><a href="https://hackerpaper.kaipfister.de/p/1707.04757/">Paper and discussion history</a>.
