It depends on what you count as “direct”. But if you consider all employees of GiveWell-supported charities, for example, I think you’d get to 1000. You can get to 100 just by adding up employees and full-time contractors at CEA, 80K, Open Phil, and GiveWell. CHAI, a single research organization, currently has 42 people listed on its “people” page, and while many are professors or graduate students who aren’t working “full-time” on CHAI, I’d guess that this still represents 25-30 person-years per year of work on AI matters.
