AI suggested 40,000 new possible chemical weapons in just six hours

It took less than six hours for drug-developing AI to invent 40,000 potentially lethal molecules. Researchers put AI normally used to search for helpful drugs into a kind of “bad actor” mode to show how easily it could be abused at a biological arms control conference.

All the researchers had to do was tweak their methodology to seek out, rather than weed out toxicity. The AI came up with tens of thousands of new substances, some of which are similar to VX, the most potent nerve agent ever developed. Shaken, they published their findings this month in the journal Nature Machine Intelligence.

The paper had us at The Verge a little shook, too. So, to figure out how worried we should be, The Verge spoke with Fabio Urbina, lead author of the paper. He’s also a senior scientist at Collaborations Pharmaceuticals, Inc., a company that focuses on finding drug treatments for rare diseases.
