Open Phil has given a total of $140 million to “Potential Risks from Advanced Artificial Intelligence” over all time.
By comparison, some estimates from Nature have “climate-related financing” at around $500 billion annually. That’s around 10,000x higher.
So even if you think that Climate Change is much more pressing that AI Safety, you might agree that the latter is much more neglected.
Also note that the majority of that Open Phil funding went to either CSET or Open AI. CSET is more focused on short-term arms races and international power struggles, Open AI only has a small safety team. So even of the $140 million, only a bit is going to technical AI Safety research.
