Self-replicating AIs are a great digital horror story – here’s the reality
Anthropic announced that an AI could self-replicate inside smart devices within months, stoking fear around the internet. Columnist Jacob Aron explains the technical limitations that make this spook story less than likely
Self-replicating artificial intelligence often appears in digital horror stories, but the reality is quite different. Recently, Anthropic claimed that self-replicating AIs could be just months away, but this seems unlikely based on the facts.
Anthropic researchers William Zhou and Daniel Freeman installed a small AI model, Gemma4-26B-A4B, on 15 Android TV boxes. Despite this setup, the model could only produce 0.39 tokens per second, roughly equivalent to 18 words per minute. This is significantly slower than human speech.
When the team attempted to have the model replicate itself, it failed. In four out of five tests, a smaller model called GLM-5.2 was able to replicate a larger model, Llama3.1-8B, but this was far from self-replication. The claim that self-replicating AIs could be "months away" comes from extrapolating data from the experiment, which is not a reliable basis for such a prediction.
The idea of an AI worm is not much more promising. An AI worm would need to transfer large files, making it more noticeable and easier to shut down. The computing power required would be minimal, and it would likely cost more than $100 an hour to achieve the same computing power as a few hundred thousand GPUs. There is no clear benefit for cybercriminals to develop an AI worm, as traditional worms like WannaCry have already caused significant damage and resulted in substantial financial losses.
