No one can say that AI will end humanity: researchers disagree, and the evidence does not establish extinction as likely or imminent. The useful question is what safeguards can reduce serious risks—from present-day misuse to future systems that might be difficult to control—and how to put those safeguards in place without treating uncertain scenarios as settled fact.
What does “existential risk” mean in the AI debate?
In plain language, an existential risk is a danger that could cause irreversible harm to humanity’s future. Experts do not use the term in exactly the same way. In a 2024 RAND panel, one participant rejected the idea that AI would cause irreversible harm, while another treated the loss of meaningful human activity as existential harm. That difference matters: a claim about humanity’s extinction is not interchangeable with a claim about profound, lasting changes to human life.
The UK Government Office for Science’s synthesis of expert engagement and desktop research conducted from April to September 2023 says there is insufficient evidence to rule out an existential threat in some future frontier-AI scenarios. It also reports that many experts consider such an outcome highly unlikely. The synthesis describes a conditional pathway, not a prediction: a system would have to outpace mitigations, gain control over critical systems, and avoid being switched off.
One 2024 survey helps show the range of concern, but it should not be mistaken for a forecast. Katja Grace and coauthors surveyed 2,778 researchers who had published in top-tier AI venues. They report that 38%–51% of respondents assigned at least a 10% chance to advanced AI leading to outcomes as bad as human extinction. Those are respondents’ subjective probability estimates under the survey’s wording—not an objective probability, a finding that extinction is likely, or a census of everyone working in AI.

How could advanced AI create extreme risks?
Misaligned objectives and growing capability
Stuart Russell, a distinguished professor of computer science at UC Berkeley, describes a central concern as a mismatch between a system’s objectives and human goals. If a system became much more capable while pursuing an objective that did not adequately reflect human intent, that mismatch could matter more—especially if the system had access to tools or real-world infrastructure.
In a Berkeley News interview, Russell and Michael Cohen used access to accounts, robotic labs, automated manufacturing, and weapons as examples of why deployment context matters. These are illustrative scenarios raised in an interview, not evidence that today’s systems are pursuing such plans.
Misuse, errors, and deployment choices
Extreme future scenarios are only one part of the risk picture. The UK synthesis identifies nearer harms including mis- and disinformation, cyber-attacks, fraud, access to harmful information, and biased decisions. It also emphasizes that outcomes depend on more than a system’s label: capability, use, ownership, access, safety measures, geopolitics, and public attitudes all play a part.

Today’s models still have limitations and make errors, according to the UK synthesis. Robust autonomy would require improvements in accuracy, reasoning, planning, memory, and self-correction. That distinction helps keep the debate grounded: examples of what a future system might do should not be presented as evidence that current systems can already do it.
What does “the AI race” mean?
Here, “race” refers to concern that competition among companies or countries could create pressure to develop or deploy increasingly capable systems quickly, potentially before safeguards are adequate. The cited sources offer competing policy perspectives; they do not establish that a particular race dynamic has been empirically proven.
Future of Life Institute (FLI) argues that racing without safeguards is dangerous and advocates a moratorium on developing superhuman AGI or superintelligence until satisfactory, provable safety guarantees are available. Anthropic, a company, argues for targeted regulation and responsible scaling, including transparency, published evaluations, verification, and flexible incentives. These are attributed advocacy and policy positions, not neutral findings or guarantees that either approach will work.

What could reduce the risks?
No single measure can guarantee safety. The proposals below address different points in the development and deployment process, and they differ in how quickly they can respond to new evidence, who must comply, and how much independent scrutiny they require.
| Approach | What it would do | Key question or trade-off |
|---|---|---|
| Independent threat assessment | RAND panelists call for high-quality research on short- and long-term risks and better science of threat assessment. | How can assessments remain credible, independent, and useful as systems and deployment contexts change? |
| Evaluations before scaling or release | Anthropic proposes capability thresholds tied to safeguards, risk evaluations for each new generation, and ways to verify public claims. | Who sets thresholds, checks the evaluations, and decides what happens when a system crosses one? |
| Adaptable rules and incentives | Anthropic presents responsible scaling policies as a possible prototype for regulation, alongside transparency, incentives for better practices, and focused rules that can evolve. | Voluntary company policies can move quickly, but how would requirements be made enforceable and applied consistently? |
| Safety requirements or a pause | FLI advocates a moratorium on developing superhuman AGI or superintelligence until satisfactory and provable safety guarantees exist, and supports safety requirements before scaling. | How would a pause be defined, verified, and coordinated, and what counts as a satisfactory guarantee? |
| Caution around critical infrastructure | RAND panelists suggest avoiding overly rapid integration of AI into critical infrastructure and continuing threat analysis. | Which uses require additional safeguards, and how can those safeguards preserve reliability without blocking beneficial applications? |
| Mitigation of current harms | The UK synthesis points to work on misuse, information harms, cyber-attacks, fraud, harmful information access, and biased decisions. | How can institutions address demonstrable harms now while also preparing for less certain future scenarios? |
How should these proposals be judged?
Comparing measures is more useful than asking whether a single policy “solves” AI risk. A proposal can be assessed against a few practical questions:
- Is it voluntary or enforceable? A company’s own policy may be faster to adopt, while enforceable rules can set obligations beyond one organization.
- Does it act before or after dangerous capabilities appear? Thresholds and pre-deployment evaluations aim to intervene before scaling or release; incident response addresses harms after they emerge.
- Can outsiders inspect the evidence? Transparency is useful only if evaluations and safety claims can be scrutinized, and verification can test whether public claims match practice.
- Can it adapt? Requirements need a way to change as capabilities, evidence, and deployment settings change.
- What does it mean for competition and innovation? Safety obligations may affect the pace and cost of development. Policymakers need to consider those effects alongside the risks of moving too quickly.
- Does it cover present harms as well as extreme future scenarios? Focusing only on hypothetical catastrophe can leave current misuse and unfair outcomes insufficiently addressed.
These questions also clarify the difference between Anthropic’s emphasis on targeted, adaptable rules and FLI’s call for a moratorium until provable safety guarantees are available. The positions differ on how restrictive action should be and when it should occur; the sources do not establish that either proposal is a proven solution.

Why technical safeguards are not enough
The UK Government Office for Science synthesis says safety cannot be resolved through technical interventions alone. Developers may improve evaluations and safeguards, but decisions about deployment, access, oversight, and acceptable risk involve institutions and the public as well as engineers. The synthesis assigns roles to industry, academia, civil society, governments, and the public.
Russell’s proposed principle captures one way to connect safety to incentives: “I think the only way forward is to figure out how to make AI safety a condition of doing business.” He made that statement in a Berkeley News interview published April 9, 2024. It is a policy view, not evidence that a particular regulatory design is already in place or effective.

Similarly, the Center for AI Safety’s statement—“Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war”—expresses a call to action, not a scientific consensus finding. A 2024 review article reported that many researchers, including Geoffrey Hinton and Yoshua Bengio, signed it.
What a practical response looks like
A grounded approach does not require certainty about whether the most extreme scenario will happen. It means improving threat assessment, testing systems before deployment and scaling, making important safety claims open to scrutiny, setting rules that can adapt, and avoiding hasty integration into critical infrastructure. It also means addressing harms already identified—such as fraud, cyber-attacks, disinformation, and biased decisions—rather than allowing speculative future risks to crowd them out.
The central policy challenge is to make safety a real constraint on development and deployment while responding proportionately to evidence. The disagreement among researchers is a reason to assess risks and safeguards carefully, not a reason to present extinction either as inevitable or as impossible.
