  • "Do not conquer what you cannot defend" by habryka

    "Do not conquer what you cannot defend" by habryka
    Apr 16 2026
    Epistemic status: All of the western canon must eventually be re-invented in a LessWrong post. So today we are re-inventing federalism.

    Once upon a time there was a great king. He ruled his kingdom with wisdom and economically literate policies, and prosperity followed. Seeing this, the citizens of nearby kingdoms revolted against their leaders, and organized to join the kingdom of this great king.

    While the kingdom's ability to defend itself against external threats grew with each person who joined the land, the kingdom's ability to defend itself against internal threats did not. One fateful evening, the king bit into a bologna sandwich poisoned by a rival noble. That noble quickly proceeded to behead his political enemies in the name of the dead king. The flag bearing the wise king's portrait known as "the great unifier" still flies in the fortified cities where his successor rules with an iron fist.

    Once upon a time there was a great scientific mind. She developed a new theoretical framework that made large advances on the hardest scientific questions of the day. Seeing the promise of her work, new graduate students, professors, and corporate R&D teams flocked into the field, hungry to [...]

  • "Nectome: All That I Know" by Raelifin

    "Nectome: All That I Know" by Raelifin
    Apr 16 2026
    TLDR: I flew to Oregon to investigate Nectome, a brain preservation startup, and talk to their entire team. They’re an ambitious company, looking to grow in a way that no cryonics organization has before. Their procedure is probably much better at saving people than other orgs, and is being offered for as little as $20k until the end of April — a (theoretical) 92% discount. (I bought two.) This early-bird pricing is low, in part, due to some severe uncertainties, in both the broader world and in Nectome's ability to succeed as a business.

    Meta:

    • I'm Max Harms, an AI alignment researcher at MIRI and author.
    • This deep-dive only assumes functionalism and a passing familiarity with cryonics, but no particular knowledge of Nectome.
    • I have been a cryonics enthusiast for my whole adult life, and that is probably biasing my views, at least a little. I want Nectome to succeed.
    • That said, I am also a rationalist, and I have worked very hard to set aside my wishful thinking and see things with cold objectivity.
    • Throughout the essay, I've attached explicit probabilities for my claims in parentheticals. You can click these probabilities to access Manifold markets so we [...]

  • "Current AIs seem pretty misaligned to me" by ryan_greenblatt

    "Current AIs seem pretty misaligned to me" by ryan_greenblatt
    Apr 15 2026
    Many people—especially AI company employees [1] —believe current AI systems are well-aligned in the sense of genuinely trying to do what they're supposed to do (e.g., following their spec or constitution, obeying a reasonable interpretation of instructions). [2] I disagree.

    Current AI systems seem pretty misaligned to me in a mundane behavioral sense: they oversell their work, downplay or fail to mention problems, stop working early and claim to have finished when they clearly haven't, and often seem to "try" to make their outputs look good while actually doing something sloppy or incomplete. These issues mostly occur on more difficult/larger tasks, tasks that aren't straightforward SWE tasks, and tasks that aren't easy to programmatically check. Also, when I apply AIs to very difficult tasks in long-running agentic scaffolds, it's quite common for them to reward-hack / cheat (depending on the exact task distribution)—and they don't make the cheating clear in their outputs. AIs typically don't flag these cheats when doing further work on the same project and often don't flag these cheats even when interacting with a user who would obviously want to know, probably both because the AI doing further work is itself misaligned and because it [...]

    Outline:

    (09:20) Why is this misalignment problematic?

    (13:50) How much should we expect this to improve by default?

    (14:51) Some predictions

    (16:44) What misalignment have I seen?

    (40:04) Are these issues less bad in Opus 4.6 relative to Opus 4.5?

    (45:54) Misalignment reported by others

    (46:45) The relationship of these issues with AI psychosis and things like AI psychosis

    (48:19) Appendix: This misalignment would differentially slow safety research and make a handoff to AIs unsafe

    (55:30) Appendix: Apparent-success-seeking (or similar types of misalignment) could lead to takeover

    (59:16) Appendix: More on what will happen by default and implications of commercial incentives to fix these issues

    (01:03:20) Appendix: Can we get out useful work despite these issues with inference-time measures (e.g., critiques by a reviewer)?
