Claim and evidence Close ×
The post “Irretrievability; or, Murphy's Curse of Oneshotness upon ASI” (2026-05-04) contests Y27. Answering the objection that experience with earlier AIs can inform models of superintelligence, he argues that the jump to superintelligence capable of killing us changes conditions far more than lab tests differ from real use, and that the lethal case cannot be tested safely.

Date 2026-05-04 · publication Role Contesting, Later restatement Register (kind of text) Nonfiction Engagement Engages a premise. Under the message-level rule, the passage, read with the paragraph, message or dialogue turn it belongs to, gives a reason against the premise that results from safe experiments on weaker systems will carry over to dangerous ones. Scope and limits Premise addressed: Results from safe experiments on weaker systems will carry over to dangerous ones. The same section says the oneshotness warning is misread as claiming that humanity "should attempt to learn zero things by looking at earlier AIs"; his claim is that such learning must generalise across the shift, not that experiments are useless.
