SIAI does not presently exhibit high levels of transparency and accountability... For this reason together with the concerns which I express about Existential Risk and Public Relations, I believe that at present GiveWell's top ranked charities VillageReach and StopTB are better choices than SIAI

• Suppose SIAI were a thousand times less accountable than VillageReach.
• Suppose this made SIAI a million times less effective than it could be.
• Suppose that even the most efficient Existential Risk charity could only reduce P(uFAI|AGI) by 10^-9
• Suppose the odds of an AI singularity or 'foom' were only 10^-9.
• Suppose a negative singularity only set mankind back by 100 years, rather than paperclipping the entire light cone and destroying all human value together.*

Even then the expected lives saved by SIAI is ~10^28.

• It's patently obvious that SIAI has an annual income of less than $10^6.

• Suppose the marginal dollar is worth 10^3 times less than the average dollar.

Even then a yearly donation of $1 saves an expected10^18 lives.

A yearly donation of £1 to VillageReach saves 100,000,000,000,000,000,000 fewer people.

*Sorry Clippy, but multifoliaterose is damaging you here; SIAI is a lot more amenable to negotiation than anyone else.
