Doom Debate with @VitalikButerin has dropped: Will “d/acc” Protect Humanity from Superintelligent AI? Vitalik is both a hardcore techno-optimist and builder, and someone willing to seriously consider AI regulation and coordination mechanisms. He coined the term "d/acc'" – defensive, decentralized acceleration – as a middle path between uncritical AI acceleration and total pause scenarios. We debate the tractability of AI alignment, whether approaches like d/acc would actually work when superintelligence arrives, and why he thinks a pluralistic world of competing AIs might be safer than a single aligned superintelligence. The crux of our disagreement is that I think we're heading for a "plants vs. animals" scenario where AI will simply operate on timescales we can't match, while Vitalik believes we can maintain agency through the right combination of defensive technologies and institutional design. Finally, we tackle the discourse itself – I ask Vitalik to debunk the common ad hominem attacks against AI doomers, from "it's just a fringe position" to "no real builders believe in doom." His responses carry weight given his credibility as both a successful entrepreneur and someone who's maintained intellectual honesty throughout his career. Big thanks to Vitalik for a good-faith debate!
