If you are optimistic about this given your expertise, I am very glad to hear it. As someone scientific but with little background in biology, I've been concerned about the bioweapons angle for a long time (and not because AI companies tell me to worry about it). Can you please explain a bit more about why you are not concerned? Between standard bioweapons like sarin and gain-of-function research on viruses, it's not obviously implausible to me that LLMs a few generations from now won't be able to guide a determined layperson through the steps needed to make something very destructive.
