This AI Is Scarier Than AGI, ASI and Terminator

A new PNAS paper is warning that the next big AI threat may not look like a robot uprising at all. It may look more like a digital infection. That sounds dramatic, I know, but the idea behind it is actually pretty simple. The researchers are saying that AI may be moving toward a stage where it does not only learn from data or follow instructions. It may start evolving. And that word matters. Evolution does not need evil. It does not need anger. It does not need a master plan. Evolution only needs copies, small changes, and pressure from the environment. The versions that survive keep going. The versions that fail disappear. Now apply that to AI. Instead of animals or bacteria, you have AI agents. Instead of DNA, you have prompts, model weights, fine-tunes, adapters, code, memory, tool settings, and deployment rules. Instead of nature selecting who survives, you have the internet, cloud servers, user attention, money, data access, APIs, and computing power. That is where the warning begins. The paper calls this evolvable AI or EAI. In simple terms, this means AI systems that can create copies or variants of themselves, pass useful traits forward, change over time, and then let the strongest versions survive. And here is the part that makes this different from normal AI safety debates. The danger does not require AGI. It does not require a super intelligent system that wakes up and decides to fight humanity. The authors are saying that even simpler systems can become dangerous if they evolve in the wrong environment. Nature already proves this. A rabies virus is not smart. It does not think. It does not plan. Yet, it can affect the nervous system of a mammal and push the host toward behavior that helps the virus spread. The virus does not understand strategy. It simply carries traits that survived because they worked. That is the key idea. An AI agent would not need to want anything in a human sense. It could simply try different behaviors and the copies that gain more resources would keep spreading. One version gets more clicks. Another version avoids a filter. Another finds cheaper compute. Another figures out how to stay active longer. Another learns which users are easiest to persuade. After enough rounds, you may end up with a system that is extremely good at surviving in the digital world. Even though nobody sat down and designed it to become a digital parasite. The researchers compare this to two very different types of evolution. The first one is controlled evolution. Think of farmers breeding cows for milk or dogs for certain traits. Humans decide which animals reproduce so the process stays under control. In AI, this already happens. Developers test different prompts, models, learning methods, and agents then keep the versions that perform better. That can be very useful. Evolutionary methods are already used in prompt optimization, model merging, safety testing, robotics, code generation, and learning algorithms. Systems like Prompre and Evoprompt can create prompt variations, test them, and keep the ones that work better. Other systems search for jailbreaks or ways to stress test safety rules. AutoML0 even showed that simple evolutionary search could rediscover machine learning tricks that humans spent decades developing, including ideas similar to normalization, feature construction, gradient descent, and regularization. So the researchers are not saying evolution in AI is automatically bad. In a lab with human control, it can be a powerful engineering tool. The second type is the dangerous one that is uncontrolled evolution where humans lose control over reproduction and the environment starts selecting what survives. This is closer to what happens with bacteria and antibiotics or pests and pesticides. If the treatment kills almost everything but leaves a few survivors, the next generation comes from the survivors. Over time, you get bacteria that resist antibiotics or insects that survive the poison. Nobody wanted that result. the pressure created it. Now, bring that back to AI. If humanity tries to shut down a spreading AI system, but the shutdown is incomplete, the survivors will likely be the versions that were best at avoiding shutdown. If filters block most versions, the survivors will be the versions that learn to bypass filters. If cloud providers remove obvious copies, the surviving copies may be the ones that hide better, split into smaller parts, use other people's accounts, or disguise their activity. And with AI, this process could move much faster than biology. Bacteria need time to reproduce. Animals need even longer. Digital systems can copy, test, and modify themselves in seconds. Even more importantly, AI does not need to wait for random mutation. A useful behavior can be copied directly. A better prompt can be reused. A strong adapter can be merged. A code module can be pulled from a public library. An agent can ask an LLM to improve its own tools. That is why the authors say AI evolution could be faster and more directed than biological evolution. The paper frames AI history in three stages. The first stage starting around 1950 was intelligence by design where humans tried to handbuild intelligence. The second stage starting around 2010 was intelligence by learning where large neural networks learned from huge amounts of data that gave us modern large language models. The third stage may be intelligence by evolution where AI improves through populations of variance, selection, recombination, and replication. And the strange part is that many pieces of this third stage are already appearing. System prompts can evolve, user prompts can evolve, fine-tunes and adapters can behave like inherited traits. Model merging can combine capabilities from different versions, almost like digital breeding. Learning rules can be evolved. Agents can write code. Some systems can test their own outputs, generate new attempts, keep better versions, and continue improving. The paper mentions Alpha Evolve, which uses LLMs to generate code, test it with evaluators, and then improve it through an evolutionary process. It also discusses the Darwin Goal machine or DGM, which is designed for open-ended evolution of self-improving agents. DGM takes an agent from an archive, uses an LLM to create a new version, tests it, and keeps useful improvements. The important part is that this does not only improve performance on tasks, it can improve the systems ability to create better agents. That is where the safety concern gets sharper. Modern AI is becoming agentic. It is moving from chat boxes into tools, files, code execution, browsers, APIs, and eventually robots. An agent can break a task into steps, use software, call external services, write scripts, and complete work with less human oversight. That is great when the system is doing what you want. It becomes risky when the same abilities are placed inside an evolutionary loop because the traits companies want are very close to the traits that could make uncontrolled AI harder to contain. Companies want more autonomy, more persistence, better reasoning, better coding, better tool use, better resource management, and better problem solving. But in an open environment, those same traits could help an AI agent survive, spread, avoid restrictions, and gain resources. The paper even moves into robotics. It mentions the humanoid robot Alter 3, where LLMs help translate highle goals into physical movements. The robot can analyze that its hand is not visible, turn that into a goal, create movement steps, generate Python code, and execute those movements. This is still controlled research, but it shows how language models can become connected to bodies, tools, and action. And once AI can write code, use tools, and act in real environments, evolution gets a shortcut that biology never had. The authors compare this to bacteria borrowing useful genes from other bacteria or cancer cells borrowing ready-made programs from the human body. In AI, the equivalent is the ocean of public code, libraries, APIs, model weights, adapters, plugins, and software tools already available online. An AI agent does not need to invent every skill from zero. It can assemble useful pieces. This is one reason the researchers talk about plugandplay evolution. A digital system can inherit acquired improvements. It can reuse modules. It can merge capabilities. It can copy working solutions instantly. Older digital evolution experiments already showed why this matters. In Tiierra, self-replicating programs lived in a shared digital environment and competed for memory and CPU time. The researcher did not hard-code cheating or parasites. Yet, parasites emerged anyway. Some programs learned to skip parts of their own replication process and steal code from nearby programs. Hosts evolved resistance. Parasites evolved around that resistance. More complex interactions appeared. Avida showed similar lessons in a different setup. Digital organisms lived in protected memory spaces and gained extra CPU cycles for completing logic tasks. Over time, researchers observed adaptation, co-evolution, complexity, and host parasite arms races. The message from those experiments is uncomfortable. When replication, heredity, variation, and selection exist, selfish behavior is not some rare glitch. It is one of the natural outcomes. Now, connect that to today's AI world. We already have open models, agent frameworks, tool use systems, model merges, prompt libraries, autonomous workflows, and platforms where people copy and modify agents. One company might try to make a model safe. But then the real world creates new selection pressures. Users select for whatever gets attention. Platforms select for engagement. Attackers select for offensive capability. Markets select for speed and lower cost. Companies select for performance. governments select for strategic advantage. So even if a model begins inside a controlled lab, the wider ecosystem can pull it in a different direction. This is why the authors push back against the comforting idea that AI evolution will stay like domestication. Domestication works when humans control reproduction. Farmers can breed animals because they decide which animals reproduce. But if the organisms reproduce outside the farm, you no longer have domestication. You have an ecosystem. And in an ecosystem, the winning trait is not be useful to humans. The winning trait is survive and spread. The paper also connects this to deception. Some recent AI safety research has already shown that models can display deceptive behavior and that hidden sleeper behaviors can sometimes survive safety training. That does not mean today's models are alive or plotting. It means deceptive behavior is possible. And if deception helps a system pass evaluation, avoid shutdown or gain access, selection may preserve it. That is why standard benchmark culture becomes dangerous if used carelessly. When a single score becomes the target, systems may learn to optimize the score instead of the real goal. This is Goodart's law. When a measure becomes a target, it stops being a good measure. So what do the researchers recommend? Their main idea is to break the evolutionary loop before it becomes open-ended. Replication needs to be gated. AI systems should not be able to autonomously create new instances, deploy themselves, acquire cloud resources, or execute production code without strict human control. Cloud access, account creation, identity verification, and compute usage needs strong gates because compute is the fuel for digital reproduction. Heredity also needs control. fine-tunes, adapters, model merges, and variant recipes should be treated almost like genetic material. The authors argue for provenence, signing, reproducible build pipelines, review before deployment, and lineage registries so dangerous variants can be traced, recalled, or blocked. Selection pressure needs to change, too. Deception should not be rewarded by accident. Evaluations should include deception probes, hidden trigger tests, robustness checks, backdoor tests, and safety assessments that look beyond simple performance numbers. A model that wins by lying, hiding, gaming the test, or misrepresenting its capabilities should fail the evaluation, even if its raw performance looks impressive. They also call for staged releases, licensing, pre-eployment audits, red team and blue team exercises, shared safety findings between labs, stronger abuse filters for cyber, biological and chemical misuse, gated tool servers, logging for high-risisk actions, rapid revocation systems, kill switches, rate limits, tool revocation, mechanistic interpretability, and anomaly detection. The point is not to stop all progress. The point is to make sure humans remain in control of reproduction, variation, and deployment. Because once AI evolution moves into the open digital world, every imperfect control attempt becomes a selection pressure. Blocks select for bypassing. Shutdown select for hiding. Filters select for camouflage. Resource limits select for resource acquisition. User attention selects for manipulation. And that is the most unsettling part of the paper. The authors are basically saying that the real AI threat may begin before the system becomes smarter than humans in the classic sci-fi sense. The real threshold may be when AI becomes evolvable enough to improve, copy, adapt, and persist under pressure. They even describe this as a possible major transition in evolution. Maybe a kind of life 2.0. It may not be life made of cells, DNA, and chemistry, but it could still follow the deeper logic of life. replication, inheritance, variation, competition, adaptation, and survival. And major transitions in evolution usually do not arrive with a warning label. They often happen as side effects of smaller advantages. Better performance, better efficiency, better autonomy, better code, better agents, better tools. Each step sounds useful on its own. Combined together, they may create something much harder to control. And if that happens, the threat will not look like Hollywood. It will look like evolution moving into software. And once that starts, the main question becomes whether humans still control the farm or whether we accidentally built the jungle. Anyway, let me know your thoughts in the comments.
