Why Matthew's PDOOM Is 2.6%

Get ready for a rematch with the one & only Bentham’s Bulldog, a.k.a. Matthew Adelstein! Our first debate covered a wide range of philosophical topics.

Today’s Debate #2 is all about Matthew’s new argument against the inevitability of AI doom. He comes out swinging with a calculated P(Doom) of just 2.6% , based on a multi-step probability chain that I challenge as potentially falling into a “Type 2 Conjunction Fallacy” (a.k.a. Multiple Stage Fallacy).

We clash on whether to expect “alignment by default” and the nature of future AI architectures. While Matthew sees current RLHF success as evidence that AIs will likely remain compliant, I argue that we’re building “Goal Engines” — superhuman optimization modules that act like nuclear cores wrapped in friendly personalities. We debate whether these engines can be safely contained, or if the capability to map goals to actions is inherently dangerous and prone to exfiltration.

Despite our different forecasts (my 50% vs his sub-10%), we actually land in the “sane zone” together on some key policy ideas, like the potential necessity of a global pause.

While Matthew’s case for low P(Doom) hasn’t convinced me, I consider his post and his engagement with me to be super high quality and good faith. We’re not here to score points, we just want to better predict how the intelligence explosion will play out.
