Roon vs. Liron: AI Doom Debate 18.12.2024

Roon is a member of the technical staff at OpenAI. He’s a highly respected voice on tech Twitter, despite being a pseudonymous cartoon avatar account. In late 2021, he invented the terms “shape rotator” and “wordcel” to refer to roughly visual/spatial/mathematical intelligence vs. verbal intelligence. He is simultaneously a serious thinker, a builder, and a shitposter.  I'm excited to learn more a...

Ben Horowitz, cofounder and General Partner at Andreessen Horowitz (a16z), says nuclear proliferation is good. I was shocked because I thought we all agreed nuclear proliferation is VERY BAD.

Getting Arrested for Barricading OpenAI's Office to Stop AI 04.10.2024

Sam Kirchner and Remmelt Ellen, leaders of the Stop AI movement, think the only way to effectively protest superintelligent AI development is with civil disobedience.
