I am a volunteer organizer with PauseAI and PauseAI US, a top forecaster, and many other things that are currently much less important.
The risk of human extinction from artificial intelligence is a near-term threat. Time is short, p(doom) is high, and anyone can take simple, practical actions right now to help prevent the worst outcomes.
I am a smaller doner (<$10k/yr) who has given to the LTFF in the past. As a data point, I would be very interested in giving to a dedicated AI Safety fund.
