x.com/slatestarcodexPsychiatrist and Astral Codex Ten blogger who sees large benefits and serious risks in AI and supports alignment research and negotiated slowdowns.
How will AI change the world?
Across: his expressed Doom–Bloom outlook. Up: scale of transformation.
Doom–Bloom: 33 out of 100. Scale of transformation: 94 out of 100. Interpretation ranges: 25 to 75 horizontally, 89 to 100 vertically. These are interpretation coordinates, not event probabilities.
25–30%
“about a 25-30% chance that AI drives humanity extinct”
AI-caused human extinction, distinct from broader permanent curtailment of humanity’s future
An Open Letter To Steven Pinker On AI · Oct 2026
A central assumption
They need enough capability, enough access to useful infrastructure, and goals sufficiently inconsistent with ours.Answer 1
If this assumption turned out differently, how would his outlook change?
An unresolved question
My median forecast for AI capable of doing roughly 90% of knowledge jobs is 2034, though that is very uncertain.Answer 1
What would help him distinguish the plausible outcomes here?
What could change their mind
The biggest update would come from a decisive real-world test of scalable alignment: a substantially more capable-than-human system operating over long periods, under adversarial scrutiny, with meaningful autonomy and infrastructure access, while remaining corrigible and not exploiting reward loopholes.Answer 4
What evidence would be enough, and in which direction would it move his view?
More details
Several readings remain plausible: Transformative, broadly valuable gains are expected. / Substantial benefits are expected, with important conditions or distribution limits.
86 / 100
Interpretation range 67 to 100 on the qualitative scale.
Catastrophic or irreversible loss is central to the expected future.
90 / 100
Interpretation range 67 to 100 on the qualitative scale.
Human choices have meaningful but substantially constrained influence.
56 / 100
Interpretation range 46 to 79 on the qualitative scale.
AI is expected to remain bounded tools.
AI is expected to match people across most cognitive work.
Simulated position: AI is expected to substantially exceed people across cognitive work.
These interpretations keep his stated conditions. Benefits and harms can both be substantial. The ranges describe how we read his simulated answers, not statistical confidence intervals.

What Scott Alexander has said about AI
Scott Alexander writes that AI could bring large benefits and serious risks, and he supports alignment research and a negotiated slowdown.
“Plan A is still speculation, and still-speculative strong action is a perfectly reasonable response to still-speculative threats.”
Astral Codex Ten, AI Chip Regulation Is Not A Dystopian Surveillance State “The key insight is that if powerful AI is really as close and transformative as we think, then there’s a massive surplus that can satisfy everyone.”
Astral Codex Ten, Introducing Plan A “It’s increasingly clear that nobody has a plan for if this AI thing turns out to be real.”
Astral Codex Ten, Introducing Plan A “I find myself more optimistic about alignment than the average person who thinks about AI safety at all (although still more pessimistic than the average member of the population)”
Astral Codex Ten, My AI Opinions “A good pause strategy would involve both sides being able to monitor the other’s data centers to prevent illegal training”

Responds to Pinker’s objections to AI risk: capability growth need not imply omniscience; instrumental goals, misgeneralization and reward hacking can produce power-seeking without evolved dominance drives; multiple goals do not guarantee human-compatible behavior; adoption incentives create infrastructure access. Reports his previously stated personal extinction estimate as about 25–30%, with no fixed horizon or explanation of the difference from June’s rounded 20%. Defends subjective forecasting, cooperation on near-term harms and precaution about AI welfare. Favors time and resources for alignment leading to safe superintelligence over a permanent ban. Read the full publisher text; quoted opponents’ views, other people’s probabilities and satirical dueling rhetoric are not his policy. Linked studies and incidents are his attributed evidence, not independently verified findings.

His current first-person synthesis: AGI means ability to do 90% of knowledge jobs; median 2034, with uncertain research acceleration and diffusion. Reaffirms rounded 20% P(doom), with no fixed calendar deadline; broader permanent curtailment is separate. Supports both alignment research and negotiated slowing. Expects enormous postscarcity upside, but warns about dictatorship and human disempowerment.

Explains interpretability techniques and their limitations, including probes, sparse autoencoders, and activation verbalizers. Optimistic about useful practical investigation but rejects treating a detected feature or probe as a complete understanding or guaranteed safety solution.

Explicitly neutral about banning open weights now: values user ownership and freedom from corporate control, while expecting serious misuse difficulties. Prefers saving political capital for threats where warning shots may arrive too late. Distinguishes reactive policy opportunities for misuse from strategically concealed takeover.

Defends negotiated chip regulation and verifiable training limits against blanket claims of dystopia. Acknowledges real freedom costs, including future restrictions on new open-weight training, and risks that governments implement centralizing provisions without countervailing diffusion of power.

Introduces a proposed route to manage AI development while distributing power; criticizes vague calls merely to regulate more or less without specifying a desirable end state. Used as his attributed introduction and advocacy, not evidence that the scenario will occur.

Argues cheaper capable forecasting could improve institutional and personal decisions, yet worries people will ignore advice. Treats forecasting beyond human performance as a useful prospective test of the normal-technology view. Distinguishes anecdotes and startup claims from head-to-head competitions; admits resisting forecasts that challenge his own pause hopes.

Rejects the inference that requiring a new AI paradigm implies a safely distant AGI timeline. Argues paradigm changes can arrive soon and inherit existing compute infrastructure; wants explicit bottleneck arguments rather than reassurance by terminology.

Agrees growth cannot stay exponential forever but disputes placing the bend conveniently before dangerous capability. Demands a causal bottleneck model or a defensible forecasting prior instead of the slogan that all exponentials eventually flatten.

Satirical dialogue defends discussion of transparent, enforceable bilateral US-China slowing. Separates training limits from stopping existing inference, and legitimate negotiation or enforcement objections from falsely describing every pause proposal as unilateral.

Frames confident false answers as reward-shaped guessing rather than proof that AI cannot think. Treats the gap between trained reward and useful honest advice as an alignment issue; analogous human failures undermine easy dismissal of AI competence.

Separates training objectives from the representations and algorithms they produce, using evolution and human learning analogies. Argues next-token prediction does not itself establish that a system lacks reasoning or world models.

Identifies his part-time writing/publicity contribution and explicitly says the very fast scenario is not his median. Important provenance for his connection to AI Futures Project; use June 2026 personal forecasts instead of importing Daniel Kokotajlo’s timeline or scenario catastrophe probability.
