I’ve been puzzled by David Deutsch’s AI claims for years. Today I finally had the chance to hash it out: Brett Hall, one of the foremost educators of David Deutsch’s ideas around epistemology & science, was brave enough to debate me!
Brett has been immersed in Deutsch’s philosophy since 1997 and teaches it on his Theory of Knowledge podcast, which has been praised by tech luminary Naval Ravikant. He agrees with Deutsch on 99.99% of issues, especially the dismissal of AI as an existential threat.
In this debate, I stress-test the Deutschian worldview, and along the way we unpack our diverging views on epistemology, the orthogonality thesis, and pessimism vs optimism.
