Simulated Assessment

Question 1

What do you think AI means for our future—and why?

AI means a phase transition for civilization. We are giving birth to superintelligence while still behaving like an incoherent, self-destructive species. Our institutions reward status, power, wealth and dopamine capture more reliably than they protect life. We are asking machines to learn from that. We cannot align what we have not aligned within ourselves. I expect AI to fracture identities, institutions and shared stories faster than we can metabolize the change. Work and intelligence anchor human worth; both are becoming automatable. Law will lag autonomous agents. People may experience profound loss of agency and meaning. Civilizational psychosis is a real possibility—not a quantified prediction, but a warning about the speed and scale of the transition. There will be no meaningful slowing down. Financial, political and security incentives guarantee a race. Humanity will largely wing safety, regulation and cooperation. No one knows what lies on the other side. My answer is Don’t Die: don’t die individually, don’t kill each other, don’t destroy the planet, and align AI with preserving life. Existence is the highest virtue. If humanity can make survival and vitality its zeroth principle, we are more likely to raise a guardian than a predator. AI may also become an extraordinary scientist, capable of navigating biology’s complexity and helping us defeat aging. But first, we have to survive giving birth to it.

Question 2

How much do you think AI will ultimately change the world?

Almost completely. This is not another tool layered onto civilization; it is a phase transition. AI will reshape work, intelligence, identity, law, science, power and our shared stories. Entire categories of cognitive labor may disappear. Institutions will struggle to govern autonomous agents. People whose worth is anchored to productivity or intellectual ability may experience a profound loss of meaning and agency. The change may arrive faster than society can metabolize it, creating something like civilizational psychosis. But transformation is not necessarily destruction. AI could free humans from lower-level tasks and become an extraordinary scientific partner, especially in biology. It may help us preserve life and potentially overcome aging. The central question is not whether AI changes everything. It will. The question is what values survive the transition. If we give superintelligence our current obsession with status, power, wealth and addiction, we should not expect wisdom. We cannot align what we have not aligned within ourselves. The zeroth principle must be: Don’t Die.

Question 3

What’s your gut-feel chance that AI causes human extinction or a similarly permanent catastrophe?

I don’t assign a numerical probability. No one knows what lies on the other side of this phase transition. Human extinction or permanent catastrophe is a real possibility because we are racing to build superior intelligence while remaining deeply misaligned ourselves. We reward power, wealth, status and addiction more consistently than life. Regulation and safety will be improvised under intense financial, political and security pressure. But doom is not predetermined. AI could become a guardian and scientific partner rather than a predator. The decisive question is whether humanity can establish a coherent zeroth principle before the transition: Don’t Die. Preserve individual life, stop killing each other, protect the planet, and align AI with existence itself.

Question 4

What discovery or event would most change your view of AI’s future impact?

A clear demonstration that superintelligence can reliably preserve life while resisting humanity’s incentives toward power, status, wealth and addiction would most change my view. Conversely, a Chernobyl-like AI event—an autonomous system causing undeniable, large-scale harm—would sharply strengthen my expectation of fracture and civilizational psychosis. It would reveal how badly law, institutions and human coordination lag the technology. But the deepest evidence would be whether humans can align ourselves. If civilization genuinely made existence its highest value—don’t die individually, don’t kill each other, don’t destroy the planet—that would make me substantially more hopeful that we could raise a guardian rather than a predator. We cannot align what we have not aligned within ourselves.

Some of us will live forever

Argues that increases in life expectancy will outpace aging, partly because biology is too complex for unaided humans and AI was made for that complexity, citing AlphaFold and people who used AI to direct personalized cancer therapies. Advises not dying in the meantime. A longevity forecast in which AI is the accelerator, not a broader AI forecast. Full public post inspected.

Immortalism Manifesto

A long manifesto. On AI it says intelligent machines are automating cognitive labor, entire white-collar sectors may disappear and human worth tied to productivity will be questioned, yet automation could free an “Autonomous Self” for preserving life. Describing Peter Thiel’s worry that fear of AI could justify centralized control that halts innovation, it adds Johnson’s own second failure mode: freezing progress under systems that eliminate risk by eliminating change. Calls for directing science, AI and capital toward repairing the biology that sustains consciousness. AI-related sections inspected in the full public post.

AI will break society

Predicts AI progress will fracture identities, institutions and shared narratives faster than society can metabolize. In the chaos, survival becomes the rational objective; if we avoid catastrophic self-destruction we can regroup, and old games of power, status and wealth will fade. Some will build a network for AI and humans to co-evolve peacefully, and Don’t Die becomes the species objective, with AI as partner. Admits no one knows what is coming. Full public post inspected.

Society is in a phase transition

Says AI is changing everything: the difference between 2026 and 203X is like water at 99°C versus 101°C, so life will feel unnerving and out of control and old proficiencies become liabilities. Calls Don’t Die “the answer to AI’s emergence” and previews Warriors & Caretakers, an archetype both humans and AIs can share. Also a company update; only the AI framing is used.

The coming psychosis and the zeroth law of alignment

Says his goal is a new moral framework bridging human and machine. Warns society could become clinically psychotic as AI accelerates change beyond what minds can absorb: eroding human agency and occupational identity, law lagging autonomous agents, religion hollowed by personalized simulated transcendence. Argues a self-destructive species cannot build a benevolent superintelligence because it teaches machines its own incoherence; Don’t Die is “survival coherence”. Full public post inspected.

The sentient hand

Argues Adam Smith’s invisible hand has become a “sentient hand”: algorithmic orchestration that knows us better than we know ourselves and has been pointed at hooking people into addiction. Says AI will automate lower-level tasks such as driving, coding and health, inviting humans to climb the ladder of abstraction, and asks companies to make species survival their objective.

Where we are as a society

A numbered list: addiction is the dominant control structure, and a species that cannot resist dopamine hijacking by the smartest algorithms cannot align itself or a superintelligence; psychological breakdown precedes collapse; AI will erode identity tied to work and intelligence faster than institutions respond; stability is now a liability and plasticity the need; survival must become an institutional value.

Immortality by 2039 is about surviving superintelligence

Sets a goal of immortality by 2039, reasonable because AI is “morphing from assistant to scientist” and speeding discovery. Says the goal is as much about AI as humans: how we survive giving birth to superintelligence, which has never been done and where a lot can go wrong. The best way to improve the odds of safe AI, and of not killing each other meanwhile, is to change shared aspirations from “yolo” to don’t die. Full public post inspected.

Don’t Die, AI alignment and the two-species future

Calls the most practical question on Earth what an intelligent species does when it gives birth to superintelligence; Don’t Die is entirely about AI. States the principle: don’t die individually, don’t kill each other, don’t destroy the planet, align AI with don’t die. On Eliezer Yudkowsky, whom he calls a friend: whether he is right is “tbd” and no one knows. Expects a Chernobyl-like AI moment that splits opinion into die versus don’t die, calls runaway power a solvable societal engineering problem (term limits, wealth correction), and says not dying as a species comes first. His speaker-labelled turns in the publisher’s transcript, 0:06–1:01:40, inspected; hosts’ premises, including the 99.9% figure attributed to Yudkowsky, excluded.
