Confidence: High, Funding needs: High

Topos is essentially Doing Math to try and figure out what to do about AI and AI Alignment. I’m very confident that they are qualified to (and actually will) turn donated money (partly via coffee) into math, in ways that might help a lot. I am also confident that the world should allow them to attempt this.

They’re now working with ARIA. That seems great.

Ultimately it all likely amounts to nothing, but the upside potential is high and the downside seems very low. I’ve helped fund them in the past and am happy about that.

To donate, go here, or get in touch at info@topos.institute.

A summit for the world's leading applied category theorists to engage with human flourishing experts.

David Spivak and Brendan Fong, the two co-founders of the Topos Institute, are applying category theory to various problems in AI alignment and other areas I think are important, and are organizing a conference to facilitate exchange between the category theory community and people currently working on various technical problems around the long-term future.

More recently various researchers I have talked to in AI alignment have found various aspects of category theory quite useful when trying to solve certain technical problems, and David Spivak has a strong track record of academic and educational contributions.
