What funding sources exist? Who are they aimed at - people within academia, independent researchers, early-career researchers, established researchers? What sort of research are they aimed at - MIRI-style deconfusion, ML-style approaches, more theoretical, less theoretical? What quirks do they have, what specific things do they target?
For purposes of this question, I am not interested in funding sources aimed at strategy/infrastructure/coordination/etc, only direct technical safety research.
