AI Ethics and Safety — A Contradiction in Terms?

A great wide-ranging conversation on AI ethics and safety with me, @mdredze.bsky.social @ruchowdh.bsky.social and of course @karaswisher.bsky.social. I don’t think putting ethics and safety together is a contradiction in terms! podcasts.apple.com/us/podcast/o...

I finally got a chance to meet @thomaslfriedman.bsky.social, whose book The World Is Flat inspired my own Rules for a Flat World. I had a great conversation with him and Andrew Freedman about the challenge we find the world facing: how do we build rules for AI that work in a complex world?

Human cooperation evolved through complex norms and institutions. Now we're introducing powerful new AI actors into our economic systems. At a recent workshop hosted at ASU we explored what evolution teaches us about getting the rules right.

Grateful to keynote at #COLM2025. Here's what we're missing about AI alignment: Humans don’t cooperate just by aggregating preferences, we build social processes and institutions to generate norms that make it safe to trade with strangers. AI needs to play by these same systems, not replace them.

Everyone, including those who think we're building powerful AI to improve lives for everyone, should take seriously how poorly our current economic indicators (unemployment, earnings, inflation) capture the well-being of low- and moderate-income folks. www.politico.com/news/magazin...
Voters Were Right About the Economy. The Data Was Wrong.
Here’s why unemployment is higher, wages are lower and growth less robust than government statistics suggest.

The most immediate need for #AISafety is more visibility by government into frontier models—we can’t determine if or how to regulate without it. The registration requirement Tino Cuéllar and Tim O’Reilly and I proposed last year is aimed at this goal. This white paper develops the proposal in depth

Despite media representations to the contrary, "women remain underrepresented among faculty in nearly all academic fields...A large-scale survey of the same faculty indicates that the reasons faculty leave are gendered, even for institutions, fields, and career ages in which retention rates are not"
Women leave academia at higher rates than men at every career stage, and attrition is especially high among three groups: tenured faculty, women in non-STEM fields, and women employed at less prestigious institutions, a #ScienceAdvances analysis finds.
Gender and retention patterns among U.S. faculty
Women faculty are more likely to leave their jobs than men, most often due to workplace climate, rather than work-life balance.
