They made hundreds and 16 worked (when synthesized by humans), seems stochastic to me. Humans do better to my knowledge (I'm out of touch but do have a relevant background). It's based on LLM architecture (using genes and proteins in place of language), also known as a stochastic parrot, which was the sense in which I was using it.

I don't deny it's a scary technology, more because of the likelihood of mistakes (or as AI companies like to say, 'hallucinations', anthropomorphising as advertising) than any intention.

As usual with this type of technology you need to be competent with the field before it becomes a force multiplier, and those people could already make viruses, and have been able to for a long time. For example, one of the previous stochastic methods was randomized mutation in a specific environment.
